  • Optical demultiplexer based on three-dimensionally periodic photonic crystals
    Patent number: 6721476
    Abstract: The invention provides photonic crystal optical demultiplexer devices produced from a three-dimensionally-periodic, porous, dielectric, photonic crystalline structure, which has surfaces or interfaces that are inverse replicas of the surfaces of a monodispersed sphere array. Such a photonic crystal optical demultiplexer comprises a three-dimensionally-periodic, porous, dielectric, photonic crystalline structure, which structure has surfaces or interfaces that are inverse replicas of the surfaces of a monodispersed sphere array, wherein necks exists between neighboring spheres in said sphere array and the average sphere diameter does not exceed about 1000 nm. A first optical waveguide is positioned to direct a broad wavelength band of incident light onto the crystalline structure. A second optical waveguide positioned to receive a narrow wavelength band of reflected light from the crystalline structure.
    Type: Grant
