    摘要： A photonic waveguide structure includes a first photonic waveguide layer located over a substrate. A sidewall cladding layer is located cladding a sidewall, but not covering a top, of the first photonic waveguide layer. A second photonic waveguide layer may be located upon the top of the sidewall cladding layer while contacting, but not straddling, the first photonic waveguide layer. The sidewall cladding layer protects the first photonic waveguide layer from environmental exposure, thus providing enhanced performance of a photonic waveguide structure. A planarizing sidewall cladding layer allows the fabrication of optical chips with multiple layers of lithographically defined devices.

    摘要： A method for constructing a thin-film infrared photodetector includes providing a thin film including ferroelectric polymer, and applying at least one electrically conductive coating to the polymer so that the coating is nonuniform in surface conductivity to thereby provide an area of higher surface resistance connected to an output region by an area of lower surface resistance.

    摘要： An assembly for measuring a trench depth parameter of a workpiece is disclosed. The assembly has an ultra-violet radiation source; a split fiber bundle having a first branch for propagating the ultra-violet radiation from the radiation source to a lens, and a second branch; a lens for focusing the UV radiation to the workpiece and refocusing an ultra-violet interference signal to the second branch; and a detector responsive to the ultra-violet interference signal received through the second branch. The detector transforms the ultra-violet interference signal to an electrical signal which is a measure of a trench depth of the workpiece. The ultra-violet interference signal is developed when ultra-violet radiation propagates through the workpiece and reflects from its base region to thereby interfere with ultra-violet radiation that is directly reflected by a workpiece surface which is different from the base region.
