摘要： An optoelectronic integrated circuit for coupling light to or from an optical waveguide formed in an optical device layer in a near-normal angle to that layer. In an embodiment, the integrated circuit comprises a semiconductor body including a metal-dielectric stack, an optical device layer, a buried oxide layer and a semiconductor substrate arranged in series between first and second opposite sides of the semiconductor body. At least one optical waveguide is formed in the optical device layer for guiding light in a defined plane in that device layer. Diffractive coupling elements are disposed in the optical device layer to couple light from the waveguide toward the second surface of the semiconductor body at a near-normal angle to the defined plane in the optical device layer. In an embodiment, an optical fiber is positioned against the semiconductor body for receiving the light from the coupling elements.

摘要： An optical spectroscopy device includes a first cladding layer is positioned over a photodetector. An optical core region is over the first cladding layer where the optical core region is configured to receive a light beam. The optical core region includes a first grating having a first pitch where the first pitch is positioned to direct a first wavelength of the light beam to a first portion of the photodetector. The optical core region further includes a second grating having a second pitch where the second grating is positioned to direct a second wavelength of the light beam to a second portion of the photodetector. The first pitch is different from the second pitch, the first wavelength is different from the second wavelength, and the first portion of the photodetector is different from the second portion of the photodetector. Additionally, a second cladding layer is over the optical core region.

摘要： In a transmission grating as a dispersive element, diffraction efficiency is enhanced and manufacturing costs are considerably reduced. A dispersive element includes resin members for forming a diffraction grating, being composed of a plurality of diffraction grating members having a cross-sectional shape respectively surrounded by two straight lines such as a triangular shape, and metal members as light-shielding members each being formed on corresponding one of the diffraction grating members at one side of the diffraction grating member along any of the straight line and the curved line of the cross-sectional shape of the diffraction grating member formed by the resin member. The metal members are configured to reduce zero-order transmitted light with respect to incident light, and to enhance diffraction efficiency of first-order transmitted light.
