20090057839 | POLYMER-EMBEDDED SEMICONDUCTOR ROD ARRAYS - A structure consisting of well-ordered semiconductor structures embedded in a binder material which maintains the ordering and orientation of the semiconductor structures. Methods for forming such a structure include forming the semiconductor structures on a substrate, casting a binder material onto the substrate to embed the semiconductor structures in the binder material, and separating the binder material from the substrate at the substrate. These methods provide for the retention of the orientation and order of highly ordered semiconductor structures in the separated binder material. | 03-05-2009 |
20090061600 | METHOD FOR REUSE OF WAFERS FOR GROWTH OF VERTICALLY-ALIGNED WIRE ARRAYS - Reusing a Si wafer for the formation of wire arrays by transferring the wire arrays to a polymer matrix, reusing a patterned oxide for several array growths, and finally polishing and reoxidizing the wafer surface and reapplying the patterned oxide. | 03-05-2009 |
20090273820 | PLASMOSTOR: A-METAL-OXIDE-SI FIELD EFFECT PLASMONIC MODULATOR - The invention is a system and method for performing all-optical modulation. A semiconductor layer having a defined thickness has an insulator adjacent one surface of the semiconductor. Conductive layers are provided adjacent the semiconductor layer and the insulator. A photodetector is provided to generate an electric field across the conductive layers in response to an input optical gate signal. An input optical signal is modulated by interaction with a plasmon wave generated at the semiconductor/conductive layer interface. By defining the thickness of the semiconductor layer, a desired wavelength of light supports the plasmon waves. Operation of the all-optical modulator requires the provision of an input optical signal of a desired wavelength and the provision of a gate optical signal. An output optical signal is recovered and can be used to store, display or transmit information, for example over a fiber optic communication system, such as a telecommunication system. | 11-05-2009 |
