A light source device includes: a plurality of light sources that generate rays of light with different wavelengths corresponding to a plurality of target wavelengths located on a designated wavelength grid; a plurality of photodetectors that detect output powers of the plurality of light sources; a plurality of optical bandpass filters that are provided between the plurality of light sources and the plurality of photodetectors; a temperature adjustment unit that adjusts a temperature of an area around the plurality of light sources; and a processor that controls the temperature adjustment unit based on output signals of the plurality of photodetectors. Widths of passbands of the optical bandpass filters are less than a wavelength spacing in the wavelength grid.
A light source device comprising:
A wavelength adjustment method that is performed by a light source device including a plurality of light sources that generate rays of light with different wavelengths corresponding to a plurality of target wavelengths located on a designated wavelength grid, a plurality of photodetectors that detect output powers of the plurality of light sources, a plurality of optical bandpass filters that are provided between the plurality of light sources and the plurality of photodetectors, and a temperature adjustment unit that adjusts a temperature of an area around the plurality of light sources, the wavelength adjustment method being a method of controlling the wavelengths of the rays of light generated by the plurality of light sources, wherein
