Abstract:
1. A photonic crystal device comprising: a substrate; a periodic structure portion formed in or on the substrate, the periodic structure portion having a plurality of holes arranged in a periodic array; at least one optical waveguide formed in or on the substrate, the at least one optical waveguide being adjacent to the periodic structure portion; and at least one optical resonator formed in or on the substrate, the at least one optical resonator being formed in a position away from the optical waveguide, with at least one of the plurality of holes of the periodic structure portion being interposed between the optical resonator and the optical waveguide, wherein the plurality of holes of the periodic structure portion include a hole having a depth different from a depth of the at least one hole interposed between the optical waveguide and the optical resonator.
