ABSTRACT:
The present invention is a method and an apparatus for resonant coupling in photonic crystal circuits. In one embodiment, a photonic crystal device comprises a substrate having a plurality of apertures formed therethrough, a photonic crystal circuit (e.g., formed by “removing” a series of apertures), and a strip waveguide extending through the apertures and coupled to the photonic crystal circuit via a surface localized photonic state formed at a surface of the photonic crystal (e.g., in the apertures). The surface localized photonic state facilitates the efficient resonant tunneling of photons from the wavelength-independent strip waveguide to the wavelength-selective photonic crystal circuit, thereby improving the filtering capabilities of the photonic crystal device.
