摘要： The light-guiding structure includes a waveguide structure that comprises a substrate and a low refractive index underclad material. The waveguide structure is oxidized to form an oxidized layer on a surface of the waveguide structure. The oxidized layer is isotropically etched after the reaction-limited oxidation regime is approaching the diffusion-limited regime and repeatedly oxidized and etched so that the waveguide structure is continuously oxidized in the reaction-limited regime, reducing the overall time of oxidation and volume of oxidized material so that the waveguide structure has its sidewall roughness reduced efficiently enabling high transmission rates of guided light.

摘要： A high-quality GaAs-type crystal thin film using an inexpensive Si wafer with good thermal release characteristics is achieved. Provided is a semiconductor wafer comprising an Si wafer; a Ge layer that is crystal-grown on the wafer and shaped as an isolated island; and a functional layer that is crystal-grown on the Ge layer. The Ge layer may be shaped as an island having a size that docs not exceed double a distance moved by crystal defects as a result of annealing the Ge layer at a certain temperature for a certain time. The Ge layer may be shaped as an island having a size for which stress due to a difference relative to a thermal expansion coefficient of Si, which is material of the wafer, does not cause crystal dejects when the Ge layer is annealed at a certain temperature.

摘要： An apparatus for generating a spectral image includes a filter to receive incident light. The filter has a variable refractive index. The apparatus also includes a modulator, operably coupled to the filter, to modulate the variable refractive index of the filter so as to generate a plurality of optical patterns from the incident light. The plurality of optical patterns represents the spectral image and each optical pattern in the plurality of optical patterns corresponds to a different modulation of the variable refractive index. The apparatus further includes a detector, in optical communication with the filter, to detect the plurality of optical patterns.

摘要： An optical grating is disposed on a waveguide to redirect light from the interior of the waveguide through the opposite side of the waveguide from the grating. In one embodiment the waveguide, the grating, and an optical sensor are combined in a single monolithic structure. In another embodiment, an absorbing layer is directly connected to the waveguide in the region of the grating. In still another embodiment, efficiency of the grating is improved by having a high index contrast between the refractive index of the grating and the refractive index of the cladding disposed over the grating, and by having an appropriately sized discontinuity in the grating.
