  • Patent number: 10797194
    Abstract: A three-terminal avalanche photodiode provides a first controllable voltage drop across a light absorbing region and a second, independently controllable, voltage drop across a photocurrent amplifying region. The compositions of the absorbing region and the amplifying region may be optimized independently of each other. In the amplifying region, p-doped and n-doped structures are offset from each other both horizontally and vertically. Directly applying a voltage across a controlled region of the photocurrent path increases avalanche gain by shaping the electric field to overlap the photocurrent density. The resulting high-gain, low-bias avalanche photodiodes may be fabricated in integrated optical circuits using commercial CMOS processes, operated by power supplies common to mature computer architecture, and used for optical interconnects, light sensing, and other applications.

  • Patent number: 9153710
    Abstract: A solar power system may include a combiner module, one or more rows of solar panels connected to the combiner module, and one or more wiring circuits connecting the one or more rows of solar panels to the combiner module. Each circuit may include an inter-module wiring arrangement that connects individual solar panels to each other in series, and a return wiring arrangement that connects the inter-module wiring arrangement to the combiner module. Each inter-module wiring arrangement may be arranged such that at least some solar panels are wired to other solar panels in the same row in a substantially alternating manner, such that non-adjacent solar panels in the same row are wired directly in series to each other. This arrangement may reduce the total length of harness wires needed to connect the one or more panel rows to the combiner box, as compared with conventional wiring schemes.

  • Patent number: 9147790
    Abstract: The present invention is a method and apparatus for receiving and converting incident radiation into DC current. The method begins with selection of an antenna having a terminal tip with a sharp edge. The antenna is layered with a substrate and a first coating. A first electrode and a metallic/mCNT antenna are layered on the first coating, and a plasmonic layer is then added. A gap is formed which is bounded on one side by the terminal ends of the plasmonic layer and the first coating, and a second electrode and a second coating on the other. The second electrode is layered upon the second coating which is layered upon the substrate. A set of AC currents is induced along the length of the antenna. The method then calculates whether or not the induced AC currents are large enough to create voltages for field emission. If the voltages are large enough, then a forward bias and a reverse bias are initiated.
