    摘要: A photovoltaic device utilizing compound semiconductor materials that are stable when operated at high temperatures. Hostile environments, and in particular, thermally stressful enviornments such as those generated by use of light concentrating systems, require encapsulation of the device. Sealing of the photo-active junction, the conductive grid, the exposed semiconductor surfaces, and the pads contacting the grid away from the junction area provide such thermal stability. A heterojunction structure can be used along with barrier materials providing a conductive grid in contact with the photo-active surface thereby reducing interdiffusion of that surface with the conductive grid.

    摘要: A method and apparatus for reducing branching, reducing defects, and improving the overall surface morphology of silicon on insulator (SOI) structures produced by Zone Melting and Recrystallization (ZMR) is described. A special heater for use in preparing SOI structures formed by ZMR comprises a graphite mass having corrugations extending along one or more side walls and which may be periodic. The heater provides concentrated regions of heat which vary periodically across the length of the molten zone of the SOI structure. Alternatively, the heater comprises a stationary lower heater member upon which the wafer is placed and a movable upper heater member having corrugations. ZMR is achieved by translating the corrugated upper heater member past the wafer. In yet another alternative, a well known strip heater having a uniformly shaped movable upper member is improved by replacing the upper member with a movable upper heater member having corrugations.

    摘要: A micro-electromechanical optical switch assembly is provided for an optical network. The switch assembly includes arrays of input and output optical fibers and optical components for selecting light paths that connect any selected pair of input and output fibers. The optical components include optical switching elements, such as torsionally supported micromechanical mirrors that are electrostatically actuated to rotate to direct the light beam along the desired light path. The mirrors are bulk micromachined into a semiconductor wafer, preserving their optical qualities, and formed into a chip mated to a cover. The package incorporates alignment elements to ensure correct position and orientation of the optical components in the package.
