Abstract

The utility model discloses a V-groove type waveguide demultiplexer, which comprises a planar lightguide chip, wherein, the input end of the planar lightguide chip is connected with a single channel fiber array used for inputting optical signals; and the output end of the planar lightguide chip is connected with a fiber array used for outputting the optical signals. The V-groove type waveguide demultiplexer can satisfy the transmission requirements of different wavelengths, splits light uniformly, can uniformly distributes the signals to users, has compact structure and small size, and can be directly installed in various prior distribution boxes.

Description

A kind of V grooved waveguide splitter
Technical field
The utility model relates to a kind of optical branching device, particularly a kind of highly versatile, beam split evenly, the planar optical waveguide optical branching device of compact conformation.
Background technology
Along with the extensive application and the popularization of xPON technology, need provide more access point and higher bandwidth for Access Network, the optical branching device of finishing integrated service is the core light device of FTTX.Optical branching device is being controlled from the central office to the luminous power the local distributing frame and is being distributed, traditional optical branching device structure is simple inadequately compact, can not be directly installed in the existing various cross-connecting box, beam split is inhomogeneous, can not give the user with the signal uniform distribution, the transmission wavelength sensitivity can not satisfy the transmission needs of different wave length.
The utility model content
The purpose of this utility model provide a kind of highly versatile, beam split evenly, 1 minute 128 tunnel planar optical waveguide optical branching device of compact conformation.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of V grooved waveguide splitter is characterized in that: comprise the planar optical waveguide chip, its input end is connected with the single channel fiber array that is used for the light signal input, and its output terminal is connected with the fiber array that is used for light signal output.
Preferably, adopt UV glue fixedly connected between described chip and the fiber array.
Owing to adopted technique scheme, the utlity model has following beneficial effect:
(1) optical wavelength transmission is insensitive, can satisfy the transmission needs of different wave length (1260nm-1620nm);
(2) beam split even (homogeneity is less than 3.5dB) can be given the user with the signal uniform distribution;
(3) compact conformation, volume is little, can be directly installed in the existing various cross-connecting box, does not need particular design to reserve very big installing space.
Description of drawings
Fig. 1 is a three-dimensional structure diagram of the present utility model;
Fig. 2 is a plane structure chart of the present utility model;
Fig. 3 is an external structure of the present utility model.
Embodiment
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Shown in Fig. 1-2,1 minute 128 tunnel planar optical waveguide optical branching device, comprise 1 fen 128 tunnel planar optical waveguide chip 2, this planar optical waveguide chip is even 1 minute 128 Y type waveguide input of beam split and waveguide output, its manufacture craft adopts ion sputtering technology, guarantee Y bifurcated waveguide spacing, the 128 core waveguide separation that make planar optical waveguide chip 2 outputs in 1 minute 128 tunnel are between 127 microns, the input end of Y bifurcated waveguide adopts UV glue fixedly connected one to be used for the single channel fiber array 1 of light signal input, and output terminal adopts fixedly connected one the 128 core fibre array 3 of UV glue.
Aim at coupling and adopt conventional PLC device Alignment Process, single channel fiber array 1 and 1 minute 128 tunnel planar optical waveguide chip 2 input ends are aimed at coupling; Again the output terminal of one 128 core fibre array 3 and 1 minute 128 tunnel planar optical waveguide chip 2 is aimed at coupling, two monitor channel Insertion Loss considering the homogeneity of device and adjust 1 minute 128 tunnel planar optical waveguide chip 2 are to minimum, go up ultra-violet curing glue then, solidify with uviol lamp, device package after solidifying forms 1 minute 128 tunnel planar optical waveguide optical branching device of miniaturization as shown in Figure 3 in a cavity.The size of encapsulation back entire device can be controlled in 70 * 25 * 4 millimeters scopes, and volume is much smaller than 1 minute No. 128 optical branching device that is mixed splice type by planar optical waveguide.
Because above-mentioned 1 minute 128 tunnel planar optical waveguide optical branching device all adopts the plane light wave waveguide technology, entire device only comprises the single channel fiber array of a light signal input, 1 fen 128 tunnel planar optical waveguide chip and 128 core fibre arrays that are used for light signal output, components and parts are few, simple in structure, and manufacture craft ripe 1 minute 128 tunnel planar optical waveguide chip and the output of 128 core fibre arrays have been adopted, make entire device have following advantage: (1) optical wavelength transmission is insensitive, can satisfy the transmission needs of different wave length (1260nm-1620nm); (2) beam split even (homogeneity is less than 3.5dB) can be given the user with the signal uniform distribution; (3) compact conformation, volume is little, can be directly installed in the existing various cross-connecting box, does not need particular design to reserve very big installing space.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to embodiment of the present utility model.For those of ordinary skill in the field, can also make other multi-form variation and changes on the basis of the above description.Here can't give exhaustive to all embodiments.Everyly belong to the row that conspicuous variation that the technical solution of the utility model amplifies out or change still are in protection domain of the present utility model.
