Thereby, the moisture resistance and disturbance resistance of the semiconductor laser light source device 100 can be improved.
- the lens 21 is made of glass such as SiO2. The lens 21 collects the laser light emitted from the optical semiconductor chip 14 and makes it enter the fiber.
- the temperature control module 5 When the temperature of the optical semiconductor chip 14 changes, the oscillation wavelength changes. Therefore, it is necessary to keep the temperature of the optical semiconductor chip 14 constant. Therefore, when the temperature of the optical semiconductor chip 14 increases, the temperature control module 5 performs cooling, and when the temperature of the optical semiconductor chip 14 decreases, the temperature control module 5 generates heat. Thereby, the temperature of the optical semiconductor chip 14 can be kept constant. Heat generated in the optical semiconductor chip 14 is transmitted to the upper substrate 5c of the temperature control module 5 via the dielectric substrate 8 and the second support block 6. The temperature control module 5 absorbs heat from the optical semiconductor chip 14. The heat absorbed by the temperature control module 5 is propagated from the lower substrate 5b of the temperature control module 5 in the negative Z-axis direction via the metal stem 1, and is radiated to the lower surface side of the metal stem 1.
- the temperature sensor 16 indirectly measures the temperature of the optical semiconductor chip 14.
- the temperature sensor 16 feeds back the measured temperature to the temperature control module 5.
- the temperature control module 5 cools the optical semiconductor chip 14 when the temperature is higher than the target value, and generates heat when the temperature is lower than the target value. Thereby, the temperature of the optical semiconductor chip 14 can be stabilized.
- the temperature sensor 16 is electrically connected to the lead pin 2b via the conductor film of the ceramic block 17. If the temperature sensor 16 and the lead pin 2b are directly connected by wire, there is a possibility that the ambient temperature transmitted to the metal stem 1 from the outside world will flow into the temperature sensor 16 through the wire. For this reason, there is a possibility that the temperature sensor 16 cannot accurately measure the temperature. Therefore, by arranging the ceramic block 17 between the temperature sensor 16 and the lead pin 2b, the amount of heat flowing into the temperature sensor 16 is reduced, and the temperature sensor 16 can accurately measure the temperature.
- the light receiving element 15 performs O/E (Optical/Electronic) conversion of the optical signal into an electrical signal.
- the electrical signal is transmitted to the lead pin 2e via the connected conductive wire 19g.
- the electrical signal input to the lead pin 2a is applied to the modulator of the optical semiconductor chip 14 via the conductive bonding material 18, the signal line 9, the conductive wire 19a, the signal line 11, and the conductive wire 19b. Since the electrical signal input to the lead pin 2a is electromagnetically coupled to the metal stem 1, the metal stem 1 acts as an AC ground. When the metal stem 1 acts as an AC ground, the first support block 4 and the cap 20 connected to the metal stem 1 also act as an AC ground. Similarly, the ground conductor 10 and metal block 13 connected to the first support block 4 also serve as AC ground. Further, the ground conductor 10 is connected to a ground conductor 12 via a conductive wire 19c, and the ground conductor 12 is connected to the upper substrate 5c of the temperature control module 5 via the second support block 6. Therefore, the ground conductor 12, the second support block 6, and the temperature control module 5 also act as an AC ground.

Therefore, resonance can be suppressed or the frequency at which resonance occurs can be changed. Therefore, high frequency characteristics can be improved.
- the metal block 13 is arranged near the second support block 6 and the upper substrate 5c of the temperature control module 5, and is connected to the first support block 4 whose potential is as close as possible to the reference potential. .
- signals emitted into space from the second support block 6 and the upper substrate 5c of the temperature control module 5 can be effectively shielded and absorbed by the metal block 13.
- the metal block 13 protrudes from the side of the second support block 6 opposite to the first support block 4.
- the metal block 13 can cover a wide range of the back surface 6d of the second support block 6, and can secure a large area capable of absorbing signals. Therefore, the effect of suppressing resonance can be enhanced. Note that even if the metal block 13 is arranged so as not to protrude from the second support block 6 in the positive direction of the X-axis, the effect of suppressing resonance can be obtained.

It can be seen that in the case where the cap 20 shown by the solid line 81 is excluded, the large drop in gain disappears compared to the case where the cap 20 shown by the broken line 80 is mounted. In other words, it can be seen that the drop in gain is due to resonance with the cap 20.
