    摘要: Method and apparatus for the continuous high speed switching or modulation of light with light. A flow medium containing an active coupling medium is flowed relative to the light beams so as to continually restore the coupling medium which is degraded by interaction with the light beam, thereby maintaining the coupling medium in a desired condition for modulating a light beam. The problem of removal of heat generated by light power dissipation is eliminated by advective flow of the medium.

    摘要: Methods and structures are disclosed demultiplexing optical signals transmitted over an optical fiber into a silicon substrate and to multiple detectors. The silicon substrate has two spaced-apart surfaces and a diffractive element disposed adjacent to one of the surfaces. Each of the optical signals corresponds to one of multiple wavelengths. The optical signals are directed into the silicon substrate along a path through the first surface to be incident on the diffractive element. The path is oriented generally normal with the first surface and/or with the diffractive element, which angularly separates the optical signals such that each of the wavelengths traverses through the substrate in a wavelength dependent direction to the first surface. Each optical signal is steered from the first surface towards the second surface to be incident on different optical elements that direct them generally normal to the first surface to be incident on one of the detectors.

    摘要: An optical electronic integrated circuit (OEIC) having optical waveguides as device interconnects. An optical waveguide is formed by depositing, in an oxygen-free atmosphere, a film of semiconductor material on a semiconductor substrate at a temperature that substantially diminishes the porosity of the film and the diffusion of material from the substrate into the film. The semiconductor film, which has an index of refraction greater than that of the substrate, is etched to form the optical waveguide on the substrate. The substrate also supports a plurality of active optical devices between which the optical waveguide extends. The substrate is preferably formed from gallium-arsenide and the waveguide from germanium. The active devices may also include these materials as well as aluminum-gallium-arsenide.
