Abstract
A lightwave circuit, by which the degree of integration can be further improved by employing a multilayered structure of wiring, is disclosed. The disclosed photonic crystal multilayer substrate has portions, each portion having a slab-waveguide type photonic crystal structure, multilayered in the direction of the thickness of the substrate. In the photonic crystal structure, a photonic crystal layer is disposed between cladding layers; the photonic crystal layer is made of a photonic crystal having a two or three dimensional periodically modulated structure with respect to the effective refractive index in the order of optical wavelengths; and each cladding layer is made of a material whose effective refractive index differs from the effective refractive index of the photonic crystal layer.
