Abstract: A photonic waveguide for conducting light having first and second wavelengths, the waveguide comprising superposed first and second strips of light conducting semiconductor materials having first and second refractive indexes, wherein the second wavelength is shorter than the first wavelength and the second refractive index is higher than the first refractive index, wherein the width and height of the first strip of light conducting semiconductor material are such that the first strip of light conducting semiconductor material is adapted to confine an optical mode of the first wavelength and the width and height of the second strip of light conducting semiconductor material are such that the second strip of light conducting semiconductor material is adapted to confine an optical mode of the second wavelength but is too narrow to confine an optical mode of the first wavelength.

Abstract: An infrared photo-detector array and a method for manufacturing it are disclosed. The infrared photo-detector array contains a plurality of pyramid-shaped structures, a first light-absorbing material supporting the plurality of the pyramid-shaped structure, a carrier-selective electronic barrier supporting the first light-absorbing material, a second light-absorbing material supporting the carrier-selective electronic barrier, and a metal reflector supporting the second light-absorbing material, wherein the plurality of the pyramid shaped structures are disposed on the side of the photo-detector array facing the incident light to be detected and the metal reflector is disposed on the opposite side of the photo-detector array. The method disclosed teaches how to manufacture the infrared photo-detector array.

Abstract: An infrared photo-detector with multiple discrete regions of a first absorber material. These regions may have geometric shapes with sloped sidewalls. The detector also may include a second absorber region comprising a second absorber material that absorbs light of a shorter wavelength than the light absorbed by the multiple discrete absorber regions of the first absorber material. The geometric shapes may extend only through the first absorber material. Alternatively, the geometric shapes may extend partially into the second absorber region. The detector has a metal reflector coupled to the multiple discrete absorber regions. The detector also has a substrate containing the discrete absorber regions and the second absorber region. The substrate can further include geometric shaped features etched into the substrate, with those features formed on the side of the substrate opposite the side containing the discrete absorber regions and the second absorber region.
