摘要： A main portion 10 of an optical module 1 includes a thermoelectric cooler 21, and a chip carrier 22b placed on the cooler 21. A semiconductor light-emitting device 31, a lens 32, photodetectors 33a, 33b, and an etalon 34 are directly or indirectly mounted on the chip carrier 22b. Supporting members 36a and 36b are also fixed on the chip carrier 22b. A roof 35 is supported by the supporting members 36a, 36b and positioned above the etalon 34. The roof 35, supporting members 36a, 36b and chip carrier 22b are maintained at substantially equal temperatures by the cooler 21. As a result, the temperature of the etalon 34 is stabilized, and therefore the variation in the lock wavelength is suppressed.

摘要： In an opto-electronic integrated circuit of the present invention, in a first surface region of a semiconductor substrate, a pin-type photodiode is constituted on the basis of a photodiode layer formed on a first transistor layer. In a second surface region of the semiconductor substrate, a heterojunction bipolar transistor is constituted on the basis of only a second transistor layer separated form the first transistor layer. Since a plurality of heterojunction bipolar transistors are normally integrated for one pin-type photodiode, the thickness of the heterojunction bipolar transistors larger in number than the pin-type photodiode is set regardless of the thickness of the pin-type photodiode. The thickness of a high-resistance layer in the pin-type photodiode is set with an increased degree of freedom. When the first surface region of the semiconductor substrate is the inner region of a recessed step portion, and the second surface region of the semiconductor substrate is the outer region of the recessed step portion, a difference in thickness between the heterojunction bipolar transistor and the pin-type photodiode is absorbed by the depth of the recessed step portion. For this reason, the pin-type photodiode and the heterojunction bipolar transistor are formed to have almost the same surface level.

摘要： The present invention provides a multimode semiconductor laser module. The module comprises a multimode laser element 34, an optical filter 54, a light-receiving element 52 and a temperature regulator 24. Multimode light from the laser element 34 is transmitted through the filter 54 and then detected by the light-receiving element 52. The output of the light-receiving element 52 changes according to the degree of overlap between the oscillation wavelength spectrum of the laser element 34 and the transmission wavelength region of the filter 54. The temperature regulator 24 modifies the oscillation wavelength region toward the desired region in response to the output of the light-receiving element 52. As a result, the oscillation wavelength region is stabilized.
