ABSTRACT:
A two-dimensional photonic crystal resonator apparatus in which the power of light coupled out of the apparatus in one direction is greater than the power of light coupled out of the apparatus in the opposite direction The apparatus has a photonic crystal slab waveguide structure having a waveguide and a resonator in the vicinity of the waveguide such that light propagated through the waveguide is extracted from the waveguide through the resonator and is coupled out of the plane of the apparatus. The apparatus has upper and lower cladding layers on the photonic crystal slab waveguide structure having different indices of refraction, and the power of light coupled out of the apparatus in the direction of the cladding layer having the higher index of refraction is greater than the power of the light coupled out of the apparatus in the direction of the cladding layer having the lower index of refraction.
