Abstract
A photonic crystal device according to the present invention includes: a substrate; a periodic structure portionformed in or on the substrate, the periodic structure portionhaving a plurality of holesandarranged in a periodic array; at least one optical waveguideformed in or on the substrate, the at least one optical waveguidebeing adjacent to the periodic structure portion; and at least one optical resonatorformed in or on the substrate, the at least one optical resonatorbeing formed in a position away from the optical waveguide, with at least one holeamong the plurality of holesandof the periodic structure portionbeing interposed between the optical resonatorand the optical waveguide. The plurality of holesandof the periodic structure portioninclude a holehaving a depth different from a depth of the at least one holeinterposed between the optical waveguide andthe optical resonator
