    摘要: According to this invention, silicon-based photodetectors using waveguides formed with silicide regions can have high speed and high efficiency for near IR applications. Utilizing the unique properties of silicides, the proposed method provides a simple and elegant way to implement a photodetector design in which photogenerated carriers travel perpendicular to the direction of light propagation. Therefore, the speed and quantum efficiency of the photodetector may be optimized independently. This device configuration may be implemented in one of the two approaches: (a) waveguides formed through surface silicidation of a silicon-based layer of a substrate (b) waveguides formed through silicidation of ridge waveguide side-walls of a silicon-based layer of a substrate; The use of mature silicon technology promises low cost of production and other benefits.

    摘要: Methods and devices relating to a sensor for use in detecting and monitoring molecular interactions. A silicon waveguide sensing element is provided along with a layer of silicon. A silicon oxide layer is also provided between the waveguide element and the layer of silicon. The sensing element is adjacent to an aqueous solution in which the molecular interactions are occurring. A light beam travelling in the silicon waveguide creates an evanescent optical field on the surface of the sensing element adjacent to the boundary between the sensing element and the aqueous medium. Molecular interactions occurring on this surface affect the intensity or the phase of the light beam travelling through the waveguide by changing the effective refractive index of the medium. By measuring the effect on the intensity, phase, or speed of the light beam, the molecular interactions can be detected and monitored in real time.

    摘要: A plurality of signals are mixed in a non-linear waveguide for generating a near field sum frequency output pattern. The near field output pattern is monitored for changes which correspond to changes in the phase relationship between the plurality of signals. A grating provides a mask through which the near field pattern may propagate. Detectors positioned above the grating at predetermined locations measure the intensity of the near field pattern and a change in the phase relationship between the input signals is determined from a change in the intensity of the near field output pattern.

    摘要: A complex of a cyclodextrin and an alkane, alkene, alkyne, aromatic compound, etc. can be prepared according to the method of the present invention. These complexes can be delivered to prokaryotic and eukaryotic cells, tissues, and organs in vitro and in vivo. In this manner, the toxic, genotoxic, and mitogenic effects of these compounds can be determined. Ternary complexes further including one or more biologically active molecules in addition to an alkane, etc. can be employed to determine the modulatory effects of such biologically active molecules on these alkanes, etc.
