    Abstract: A patterned array of metallic nanostructures and fabrication thereof is described. A plurality of nanowires is grown on a substrate, the plurality of nanowires being laterally arranged on the substrate in a predetermined array pattern. The plurality of nanowires is coated with a metal to generate a plurality of metal-coated nanowires. Vacancies between the metal-coated nanowires are filled in with a sacrificial material for stabilization, and the metal-coated nanowires are planarized. The sacrificial material is removed, the patterned array of metallic nanostructures being formed by the plurality of planarized metal-coated nanowires.

    Abstract: A semiconductor nanowire is grown laterally. A method of growing the nanowire forms a vertical surface on a substrate, and activates the vertical surface with a nanoparticle catalyst. A method of laterally bridging the nanowire grows the nanowire from the activated vertical surface to connect to an opposite vertical surface on the substrate. A method of connecting electrodes of a semiconductor device grows the nanowire from an activated device electrode to an opposing device electrode. A method of bridging semiconductor nanowires grows nanowires between an electrode pair in opposing lateral directions. A method of self-assembling the nanowire bridges the nanowire between an activated electrode pair. A method of controlling nanowire growth forms a surface irregularity in the vertical surface. An electronic device includes a laterally grown nano-scale interconnection.

    Abstract: An imprinting apparatus and method of fabrication provide a mold having a pattern for imprinting. The apparatus includes a semiconductor substrate polished in a [110] direction. The semiconductor substrate has a (110) horizontal planar surface and vertical sidewalls of a wet chemical etched trench. The sidewalls are aligned with and therefore are (111) vertical lattice planes of the semiconductor substrate. The semiconductor substrate includes a plurality of vertical structures between the sidewalls, wherein the vertical structures may be nano-scale spaced apart. The method includes wet etching a trench with spaced apart (111) vertical sidewalls in an exposed portion of the (110) horizontal surface of the semiconductor substrate along (111) vertical lattice planes. A chemical etching solution is used that etches the (111) vertical lattice planes slower than the (110) horizontal lattice plane. The method further includes forming the imprinting mold.

    Abstract: A semiconductor optical amplifier (SOA) apparatus and related methods are described. The SOA comprises a signal waveguide for guiding an optical signal along a signal path, and further comprises one or more laser cavities having a gain medium lying outside the signal waveguide, the gain medium being sufficiently close to the signal waveguide such that, when the gain medium is pumped with an excitation current, the optical signal traveling down the signal waveguide is amplified by an evanescent coupling effect with the laser cavity. When the gain medium is sufficiently pumped to cause lasing action in the laser cavity, gain-clamped amplification of the optical signal is achieved. Additional features relating to segmented laser cavities, separate pumping of laser cavity segments, DFB/DBR gratings, current profiling to improve ASE noise performance, coupled-cavity lasers, avoidance of injection locking effects, manipulation of gain curve peaks, integration with a tunable vertical cavity coupler, integration with a photodetector, integration with an RZ signal modulator, and other described features may be used with the evanescent coupling case or with an SOA having a laser cavity gain medium that is coextensive with the gain medium of the signal waveguide.
