  • Patent number: 8160404
    Abstract: An optoelectronic device includes an input waveguide structure that receives an input optical signal. A GeSi/Si waveguide structure receives from the input waveguide the input optical signal and performs selective optoelectronic operations on the input optical signal. The GeSi/Si waveguide structure outputs an optical or electrical output signal associated with the selective optoelectronic operations performed on the input optical signal. An output waveguide structure receives the output optical signal from the GeSi/Si waveguide structure and provides the optical output signal for further processing.

  • Publication number: 20120025195
    Abstract: In a structure for crystalline material growth, there is provided a lower growth confinement layer and an upper growth confinement layer that is disposed above and vertically separated from the lower growth confinement layer. A lateral growth channel is provided between the upper and lower growth confinement layers, and is characterized by a height that is defined by the vertical separation between the upper and lower growth confinement layers. A growth seed is disposed at a site in the lateral growth channel for initiating crystalline material growth in the channel. A growth channel outlet is included for providing formed crystalline material from the growth channel. With this growth confinement structure, crystalline material can be grown from the growth seed to the lateral growth channel outlet.

  • Publication number: 20090171829
    Abstract: Benchmarks for the price of a financial instrument such as FX spot rate for a currency pair are calculated by an algorithm based on a previous benchmark and a market price. The market price is derived from a deal price and a quote price. The deal price is based on deals conducted since the last benchmark and the quote price is based on bids and offers entered since the last benchmark. For each of the deal and quote prices, a price, weight and scatter is calculated which is used to calculate a benchmark price, weight and scatter and a benchmark error.
