| 英文摘要 | The wavelength-variable light source comprises a semiconductor light-emitting device 11; a first light waveguide 31 optically coupled to the semiconductor light-emitting device; a plurality of second light waveguides 32, disposed in parallel to each other, in which light-waveguide-type diffraction gratings 21 having wavelengths different from each other are respectively disposed; a first optical switch 12 formed such that the first light waveguide can oppose the second light waveguides; and a condenser 13 which collects output optical powers from a plurality of second light waveguides into one beam. The semiconductor light-emitting device 11, first light waveguide 31, second light waveguides 32, and light-waveguide-type diffraction gratings 21 form a resonator 40, which oscillates light having a wavelength reflected by the light-waveguide-type diffraction gratings 2 |
