Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 2, an embodiment of the present application provides an optical coupling module, including:
the optical component comprises an optical component 1 and a filter plate 2, wherein a fiber lens 11 is arranged on a first surface, close to an optical fiber, of the optical component 1, and a receiving lens 12 and a transmitting lens 13 are arranged on a second surface, close to a laser and a detector, of the optical component 1;
the optical component 1 is further provided with a first groove 14, the filter 2 is obliquely arranged in the first groove 14, an included angle is formed between the filter 2 and one side surface, close to the first surface, of the first groove 14, and two optical surfaces (surfaces marked by 2a and 2b in the figure) of the filter 2 are plated with functional films;
the first optical signal from the fiber lens 11 is reflected to the receiving lens 12 by the functional film coated on one optical surface of the filter 2, and the second optical signal from the transmitting lens 13 is reflected to the fiber lens 11 by the functional film coated on the other optical surface of the filter 2, the first wavelength of the first optical signal and the second wavelength of the second optical signal being different.
The optical coupling module provided by the embodiment of the application is used for connecting electronic equipment and an optical fiber, and the optical coupling module can be a component of the electronic equipment. Referring to fig. 2 or 3, the fiber lens 11 is disposed opposite to the optical fiber, and the distance between the fiber lens 11 and the optical fiber may be equal to the focal length of the fiber lens 11; the receiving lens 12 is arranged opposite to the detector 3 of the electronic device, and the distance between the receiving lens 12 and the detector 3 can be equal to the focal length of the receiving lens 12; the emitting lens 13 is arranged opposite to the laser 4 of the electronic device, and the distance between the emitting lens 13 and the laser 4 can be equal to the focal length of the emitting lens 13; the detector 3 and the laser 4 are both integrated on a substrate 5 of the electronic device.
Alternatively, the substrate may be a Printed Circuit Board (PCB) or the like. The activator may be a Vertical Cavity Surface Emitting Laser (VCSEL) or the like.
The first optical signal is an optical signal emitted to the fiber lens 11 by an optical fiber, the first optical signal is transmitted to a functional film on an optical surface of the filter 2 after passing through the fiber lens 11, the functional film reflects the first optical signal to the receiving lens 12, and the receiving lens 12 converges the first optical signal on the detector 3 into a light spot and emits the light spot into the detector 3.
The second optical signal is an optical signal emitted from the laser 4 to the emitting lens 13, and the second optical signal passes through the emitting lens 13 and then is transmitted to the functional film on the other optical surface of the filter 2, the functional film reflects the second optical signal to the fiber lens 11, and the fiber lens 11 converges the second optical signal on the optical fiber into a light spot and emits the light spot into the optical fiber.
Because the gap of the included angle between the filter plate 2 and the side surface of the first groove 14 close to the first surface is air, and no other filler (such as optical glue and the like) exists, the defects (such as air bubbles and the like) in the filler can be avoided, the first optical signal is reflected to the receiving lens 12 and transmitted to the laser 4, and the performance of the laser 4 is prevented from being influenced; since the first optical signal and the second optical signal are reflected by the functional films on both optical surfaces of the filter 2, the distance between the receiving lens 12 and the transmitting lens 13 can be made smaller than that in the conventional optical coupling module, so that the volume of the optical coupling module can be reduced.
The first surface and the second surface may be perpendicular or approximately perpendicular, and the second surface where the receiving lens 12 and the fiber lens 13 are located is a plane. Assuming that the second surface is parallel or approximately parallel to the horizontal plane, since the filter 2 is obliquely placed in the first groove 14, a preset first included angle which faces the fiber lens 11 and is smaller than 90 degrees exists between the filter 2 and the second surface, so that an included angle which is smaller than 90 degrees also exists between the filter 2 and the first surface, and the included angle is equal to or approximately equal to 90 degrees minus the preset first included angle. And because the transmission path of the first optical signal from the fiber lens 11 to the filter 2 can be perpendicular to the first surface or nearly perpendicular to the first surface, the incident angle of the first optical signal on the filter 2 is also an included angle smaller than 90 degrees, and the filter 2 can reflect the first optical signal to the receiving lens 12. And in turn may be perpendicular or nearly perpendicular to the second surface due to the transmission path of the second optical signal from the transmitting lens 13 to the filter segment 2. Thus, the incident angle of the second optical signal on the filter 2 is also smaller than the included angle of 90 degrees, and the filter 2 can reflect the second optical signal to the fiber lens 11.
Alternatively, referring to fig. 2 and 3, the filter 2 may have an included angle with a side surface of the first groove 14 close to the first surface, so that the filter 2 may not contact with the side surface of the first groove 14 close to the first surface, or only one side of the filter 2 may contact with the side surface of the first groove 14 close to the first surface, but the other parts do not contact.
The optical surface of filter segment 2 refers to the surface of filter segment 2 through which light signals pass, for example, surface 2a and surface 2b of filter segment 2 shown in fig. 2 and 3 through which light signals pass, so surface 2a and surface 2b may be referred to as the two optical surfaces of filter segment 2.
Referring to fig. 2 and 3, one optical surface of the filter 2 close to the first surface is plated with a first functional film, and the other optical surface is plated with a second functional film. In implementation, there may be two implementation manners, which are respectively:
for the first implementation, referring to fig. 2, one optical surface of the filter 2 close to the first surface is plated with a first functional film, and the other optical surface is plated with a second functional film, where the first functional film is used for reflecting a first optical signal with a first wavelength and transmitting a second optical signal with a second wavelength, and the second functional film is used for reflecting the second optical signal.
In a first implementation, the receiving lens 12 is located between the emitting lens 13 and the first surface. Since the transmitting lens 13 is positioned opposite the laser 4 and the receiving lens 12 is positioned opposite the detector 3, the detector 3 is positioned between the laser 4 and the first surface. For this implementation, the first optical signal is reflected due to the first functional film of the filter 2; and the detector 3 is located between the laser 4 and the first surface, it is ensured from the structural design that no reflection of the first optical signal to the receiving lens 13 and transmission into the laser 4 occurs, avoiding an impact on the performance of the laser 4.
Thus, the first optical signal emitted by the optical fiber is transmitted to the first functional film of the filter 2 through the fiber lens 11, the first functional film directly reflects the first optical signal to the receiving lens 12, and the receiving lens 12 converges the first optical signal on the detector 3 into a light spot and emits the light spot into the detector 3.
The laser 4 emits a second optical signal to the emitting lens 13, and the second optical signal passes through the emitting lens 13, is transmitted to the first functional film of the filter 2, and is transmitted from the first functional film to the second functional film; the second functional film reflects the second optical signal to the first functional film and transmits the second optical signal from the first functional film to the fiber lens 11, and the fiber lens 11 converges the second optical signal on the optical fiber into a light beam and emits the light beam into the optical fiber.
In order to adjust the light intensity of the second optical signal, see fig. 4, the second functional film may transmit a part of the second optical signal. Thus, when the second optical signal is transmitted to the second functional film, part of the second optical signal is transmitted from the second functional film, and the rest of the second optical signal is reflected by the second functional film to the optical fiber, so that the optical intensity of the second optical signal reflected to the optical fiber can be reduced.
For a second implementation manner, referring to fig. 3, one optical surface of the filter 2 close to the first surface is plated with a first functional film, the other optical surface is plated with a second functional film, the first functional film is used for reflecting a second optical signal with a second wavelength and transmitting a first optical signal with a first wavelength, and the second functional film is used for reflecting the first optical signal.
In a second implementation, the transmit lens 13 is located between the receive lens 12 and the first surface. Since the transmitting lens 13 is positioned opposite the laser 4 and the receiving lens 12 is positioned opposite the detector 3, the laser 4 is positioned between the detector 3 and the first surface. For the implementation mode, because the gap of the included angle between the filter plate 2 and the side surface of the first groove 14 close to the first surface is air, no other filler (such as optical glue and the like) exists, it can be ensured from the design of the system architecture that the defect (such as air bubble and the like) inside the filler does not occur, the first optical signal is reflected to the receiving lens 13 and transmitted to the laser 4, and the influence on the performance of the laser 4 is avoided.
The first optical signal emitted by the optical fiber is transmitted to the first functional film of the filter 2 through the fiber lens 11 and is transmitted to the second functional film from the first functional film; the second functional film reflects the first optical signal to the first functional film and transmits the first optical signal from the first functional film to the receiving lens 12, and the receiving lens 12 focuses the first optical signal on the detector 3 to form a light spot and emits the light spot into the detector 3.
The laser 4 emits a second optical signal to the emitting lens 13, and the second optical signal is transmitted to the first functional film of the filter 2 after passing through the emitting lens 13; the first functional film directly reflects the second optical signal to the fiber lens 11, and the fiber lens 11 converges the second optical signal on the optical fiber into a light beam and emits the light beam into the optical fiber.
The first optical signal emitted by the optical fiber is divergent light, and the first optical signal is vertically emitted to the optical fiber lens 11, and the optical fiber lens 11 collimates the first optical signal and then emits the first optical signal to the filter 2. The second optical signal emitted by the laser 4 is divergent light, and is vertically emitted to the emission lens 13, and the emission lens 13 collimates the second optical signal and then emits the second optical signal to the filter 2.
For the above two implementation manners, since the first optical signal and the second optical signal are reflected by the functional films on the front and rear optical surfaces of the filter 2, the distance between the receiving lens 12 and the transmitting lens 13 can be made smaller than the distance between the two in the existing optical coupling module, so that the volume of the optical coupling module can be reduced.

The angle between the two side surfaces of the second fixing table 7 may also be a right angle or an approximate right angle, and may be 89.5 degrees, 90 degrees, 90.5 degrees, or the like, for example. Alternatively, the included angle between the two side surfaces of the second fixing table 7 may be other angles, for example, 70 degrees, 80 degrees, 85 degrees, etc.
Wherein, the included angle between the two side surfaces of the second fixing table 7 may also be equal to the included angle between the bottom surface of the first groove 14 and the side surface of the first groove 14 close to the first surface.
This cross-section of second fixed station 7 can be isosceles right triangle, and filter 2 fixes on inclined plane 61 of first fixed station 6 and inclined plane 71 of second fixed station 7 like this, can guarantee that filter 2 and the contained angle between the first surface and with the second surface between the contained angle be 45 degrees or approximate 45 degrees.
Alternatively, the second fixing stage 7 and the optical component 1 may be molded together, or the two side surfaces of the second fixing stage 7 may be fixed to the bottom surface of the first recess 14 and the side surface adjacent to the first surface, respectively, by structural adhesive.
Alternatively, the filter 2 may be fixed on the first inclined surface 61 of the first fixing stage 6 and the second inclined surface 71 of the second fixing stage 7 by structural adhesive.
In this embodiment, the filter segment 2 may also be fixed in the first recess without the first fixing table 6 and/or the second fixing table 7. In practice, as shown in fig. 2 and 3, the top of the filter plate 2 may be fixed on a side of the first groove 14 close to the first surface by structural adhesive, and the bottom may be fixed on the bottom of the first groove 14 by structural adhesive.
It should be noted that: in the optical coupling module with the above structure, when the first optical signal and the second optical signal are transmitted to a side surface of the first groove 14 close to the first surface, both the first optical signal and the second optical signal are perpendicular to the side surface of the first groove 14 close to the first surface, so that when the first optical signal is transmitted to the side surface, a part of the first optical signal is reflected back to the optical fiber by the original circuit, and when the second optical signal is transmitted to the side surface, a part of the second optical signal is reflected back to the laser 4 by the original circuit. To solve the problems, the embodiments of the present application provide the following two solutions:
in a first solution, an antireflection film is coated on a side surface of the first groove 14 close to the first surface.
After the antireflection film is plated on one side surface of the first groove 14 close to the first surface, the performance of the side surface for transmitting optical signals can be improved, and the performance of the side surface for reflecting optical signals can be reduced. Thus, when the first optical signal is transmitted to the side surface, the part of the first optical signal reflected by the side surface primary circuit can be reduced and more of the first optical signal can be transmitted from the side surface to the filter 2, and when the second optical signal is transmitted to the side surface, the part of the second optical signal reflected by the side surface primary circuit can be reduced and more of the second optical signal can be transmitted from the side surface to the fiber lens 11.
In a second solution, referring to fig. 9 and 10, a second groove 15 is disposed on a side surface of the first groove 14 close to the first surface, an incident angle of the first optical signal on a bottom surface of the second groove 15 and an incident angle of the second optical signal on the bottom surface of the second groove 15 are not equal to 90 degrees, and a transmission path of the first optical signal and a transmission path of the second optical signal pass through the bottom surface of the second groove 15.
Optionally, a preset second included angle smaller than 90 degrees exists between the bottom surface of the second groove 15 and the second surface, and the preset second included angle faces the fiber lens 11. The predetermined second included angle may be an included angle of the same value as 85 degrees, 80 degrees, 75 degrees, or 70 degrees.
In addition, there is also an angle between the bottom surface of the second groove 15 and the first surface that is less than 90 degrees, which is equal to or approximately equal to 90 degrees minus the second angle.
Referring to fig. 11, when the first optical signal is transmitted to the bottom surface of the second groove 15, because the included angle between the bottom surface of the second groove 15 and the first surface is smaller than 90 degrees, that is, the bottom surface of the second groove 15 is an inclined surface, and because the first optical signal is perpendicular or approximately perpendicular to the first surface, the first optical signal is not perpendicular or approximately perpendicular to the bottom surface of the second groove 15, and an included angle smaller than 90 degrees exists between the first optical signal and the bottom surface of the second groove 15, so that a part of the first optical signal reflected by the bottom surface of the second groove 15 cannot be transmitted along the original transmission path of the first optical signal, and the remaining first optical signal can pass through the bottom surface of the second groove 15 and be transmitted to the filter 2, thereby avoiding reflecting the part of the first optical signal back to the optical fiber.
Similarly, when the second optical signal is transmitted to the bottom surface of the second groove 15, because the included angle between the bottom surface of the second groove 15 and the second surface is smaller than 90 degrees, the second optical signal is not vertically or approximately vertically transmitted to the bottom surface of the second groove 15, and an included angle smaller than 90 degrees exists between the second optical signal and the bottom surface of the second groove 15, so that part of the second optical signal reflected by the bottom surface of the second groove 15 cannot be transmitted along the original transmission path of the second optical signal, and the rest of the second optical signal can penetrate through the bottom surface and be transmitted to the optical fiber lens 11, thereby avoiding reflecting the part of the second optical signal back to the activator 4.
Optionally, the bottom surface of the second groove 15 may also be plated with an antireflection film.
After the bottom surface of the second groove 15 is coated with the antireflection film, the performance of the bottom surface for transmitting optical signals can be improved, and the performance of the bottom surface for reflecting optical signals can be reduced. Thus, when the first optical signal is transmitted to the bottom surface, the part of the first optical signal reflected by the bottom surface can be reduced and more of the first optical signal is transmitted from the bottom surface to the filter 2, so that the loss of the optical signal can be reduced, and when the second optical signal is transmitted to the bottom surface, the part of the second optical signal reflected by the bottom surface can be reduced and more of the second optical signal is transmitted from the bottom surface to the fiber lens 11.
It should be noted that: when the first optical signal and the second optical signal are transmitted to the bottom surface of the first groove 14, the first optical signal and the second optical signal are perpendicular to the bottom surface of the first groove 14, so that when the first optical signal is transmitted to the bottom surface, a part of the first optical signal may be reflected back to the optical fiber by the original circuit, and when the second optical signal is transmitted to the bottom surface, a part of the second optical signal may be reflected back to the laser 4 by the original circuit. To solve the problems, the embodiments of the present application provide the following two solutions:
in a first solution, the bottom surface of the first groove 14 may be plated with an antireflection film.
After the bottom surface of the first groove 14 is coated with the antireflection film, the performance of the bottom surface for transmitting optical signals can be improved, and the performance of the bottom surface for reflecting optical signals can be reduced. Thus, when the first optical signal is transmitted to the bottom surface, the part of the first optical signal reflected by the bottom surface primary circuit can be reduced, and more of the first optical signal is transmitted from the bottom surface to the receiving lens 12, so that the loss of the optical signal can be reduced, and when the second optical signal is transmitted to the bottom surface, the part of the second optical signal reflected by the bottom surface primary circuit can be reduced, and more of the second optical signal is transmitted from the bottom surface to the filter 2.
In a second solution, referring to fig. 11, the incident angle of the first optical signal on the bottom surface of the first groove 14 and the incident angle of the second optical signal on the bottom surface of the first groove 14 are not equal to 90 degrees.
A preset third included angle smaller than 90 degrees may exist between the bottom surface of the first groove 14 and the second surface, that is, the bottom surface of the first groove 14 may also be an inclined surface.
The predetermined third angle may be towards the fiber lens 11 or towards another surface corresponding to the first surface of the optical component 1, and may be an angle of 10 degrees, 15 degrees, 20 degrees or 25 degrees.
An included angle of less than 90 degrees exists between the bottom surface of the first groove 14 and the first surface, and the included angle is equal to or approximately equal to 90 degrees minus a third included angle.
Referring to fig. 11, when the first optical signal is transmitted to the bottom surface of the first groove 14, because an included angle smaller than 90 degrees exists between the bottom surface and the first surface, that is, the bottom surface is an inclined surface, so that the bottom surface is not perpendicular to the first optical signal, a part of the first optical signal reflected by the bottom surface cannot be transmitted along the original transmission path of the first optical signal, and the remaining first optical signal passes through the bottom surface and is transmitted to the receiving lens 12, thereby avoiding reflecting the part of the first optical signal back to the optical fiber.
Similarly, when the second optical signal is transmitted to the bottom surface, because an included angle smaller than 90 degrees exists between the bottom surface and the second surface, the bottom surface is not perpendicular to the second optical signal, so that part of the second optical signal reflected by the bottom surface is not transmitted along the original transmission path of the second optical signal, and the rest of the second optical signal is transmitted to the filter 2 through the bottom surface, thereby avoiding reflecting the part of the second optical signal back to the activator 4.
Optionally, the bottom surface of the first groove 14 may also be plated with an antireflection film.
After the bottom surface of the first groove 14 is coated with the antireflection film, the performance of the bottom surface for transmitting optical signals can be improved, and the performance of the bottom surface for reflecting optical signals can be reduced. Thus, when the first optical signal is transmitted to the bottom surface, the part of the first optical signal reflected by the bottom surface can be reduced and more of the first optical signal is transmitted from the bottom surface to the filter 2, so that the loss of the optical signal can be reduced, and when the second optical signal is transmitted to the bottom surface, the part of the second optical signal reflected by the bottom surface can be reduced and more of the second optical signal is transmitted from the bottom surface to the filter 2.
Alternatively, referring to fig. 11, in a second solution, a power monitor 9 may be further disposed on the substrate 5, the power monitor 9 may be connected to the laser 4, and the power monitor 9 may receive a portion of the second optical signal reflected by the bottom surface of the first groove 14, and adjust the emission power of the laser 4 according to the signal intensity of the portion of the second optical signal. For example, the emission power of the laser 4 may be increased when the signal strength of the portion of the second optical signal is below a preset threshold.
Alternatively, the power Monitor 9 may be a PIN photodiode (PIN PD), a Monitor Photodiode (MPD), or the like.
Alternatively, the power monitor 9 may also be integrated on the substrate 5.
Alternatively, the distance a between the center of the receiving lens 12 and the center of the transmitting lens 13 may vary with the thickness of the filter segment 2 and/or the first angle between the filter segment 2 and the second surface.
Wherein, the thicker the filter 2 or the smaller the preset first included angle is, the larger the distance a between the center of the receiving lens 12 and the center of the transmitting lens 13 may be, and conversely, the thinner the filter 2 or the larger the preset first included angle is, the smaller the distance a between the center of the receiving lens 12 and the center of the transmitting lens 13 may be.
The angle of incidence of the first light signal on the filter segment 2 and the angle of incidence of the second light signal on the filter segment 2 may both be set to be larger than 44 degrees and smaller than 46 degrees, i.e. the first angle between the filter segment 2 and the second surface may be larger than 44 degrees and smaller than 46 degrees. For example, it may be 44.5 degrees, 45 degrees, 45.5 degrees, or the like. Or,
it is also possible to set the angle of incidence of the first light signal on the filter segment 2 and the angle of incidence of the second light signal on the filter segment 2 to other angles, i.e. the first angle between the filter segment 2 and the second surface may be other angles, for example, may be 30 degrees, 40 degrees, 50 degrees or 60 degrees, etc.
Alternatively, in general, the incident angle of the first light signal on the filter 2 and the incident angle of the second light signal on the filter 2 are both greater than 44 degrees and less than 46 degrees, that is, when the first included angle between the filter 2 and the second surface may be greater than 44 degrees and less than 46 degrees, for example, at an included angle of 44.5 degrees, 45 degrees or 45.5 degrees, the relationship satisfied between the distance a between the center of the receiving lens 12 and the center of the transmitting lens 13 and the thickness b of the filter 2 is:this makes it possible to make the interval between the receiving lens 12 and the transmitting lens 13 small and also to control the production cost well, and thus to reduce the volume of the optical coupling module.

the first portion 81 has a hollow cavity therein, and the second portion 82 has one end fixed to an end face of the first portion 81 and the other end fixed to the fiber lens 11.
Wherein a cavity within the first portion 81 can receive and secure an optical fiber. And the length L of the second portion 82 may be equal to the focal length of the fiber lens 11.
Alternatively, the first portion 81 and the second portion 82 may each be of a cylindrical configuration or the like.
Optionally, the Optical fiber may be a multimode multi-fiber or a single-mode Optical fiber, the cavity in the first portion 81 is an Optical fiber interface, and may be an LC/SC type jumper (LC/SC) interface, or may be an Active Optical Cable (AOC) interface if the Optical fiber interface is fixed.

Referring to fig. 15 and 16, when the length of the filter segment 2 is long, the distance between the first fixing stage 6 and the second fixing stage 7 is also long, so that the first optical signal from each fiber lens 11 and the second optical signal from each transmitting lens 13 can be reflected by the filter segment 2.
In the embodiment of the application, because the two optical surfaces of the filter are plated with the functional films and an included angle is formed between the filter and one side surface of the first groove close to the first surface, the first optical signal is not reflected to the receiving lens and transmitted to the laser, and the performance of the laser is prevented from being influenced; since the first optical signal and the second optical signal are reflected by the functional films on the two optical surfaces of the filter, the distance between the receiving lens and the transmitting lens can be made smaller than that between the two in the existing optical coupling module, thereby reducing the volume of the optical coupling module.
