1. An optical device comprising:

  • a compound resonator structure having a first resonator structure which produces resonance by reflecting light using a diffraction grating, and a second resonator structure which produces Fabry-Perot resonance by reflecting light using at least two surfaces, wherein an output intensity of light of a predetermined polarized wave in a first oscillation state mainly based on the resonance by said first resonator structure is different from an output intensity of light of the predetermined polarized wave in a second oscillation state mainly based on the resonance by said second resonator structure.
