摘要： An optical filter is provided on a first thermo-module whose temperature is controlled to be constant, via a base. Accordingly, a wavelength discrimination characteristic of the optical filter and an optical isolator can be stabilized, thereby realizing more accurate wavelength locking. Further, a second thermo-module is provided on the first thermo-module whose temperature is controlled to be constant. Accordingly, the temperature control range of the second thermo-module can be expanded, and hence the wavelength variable range of a semiconductor laser device provided on the second thermo-module via a base and a submount can be expanded.

摘要： In an external cavity laser, which comprises an FBG section having the Bragg wavelength of light reflected by a grating adjusted to a given wavelength and a laser light emitting device designed to generate light, optically coupled to the FBG section to ensure input and output of the light, and including a high-reflection surface for reflecting the generated light, the light is resonated by a cavity formed between the high-reflection surface and the grating, whereby a laser beam having a given oscillation wavelength is oscillated through a connector. The FBG section is located on an optical path between the laser light emitting device and the connector, and an isolator is located on an optical path between the FBG section and the connector. The isolator serves to absorb and intercept reflected waves or reflected return light from the connector.
