摘要： An optical image-driven light induced dielectrophoresis (DEP) apparatus and method are described which provide for the manipulation of particles or cells with a diameter on the order of 100 μm or less. The apparatus is referred to as optoelectric tweezers (OET) and provides a number of advantages over conventional optical tweezers, in particular the ability to perform operations in parallel and over a large area without damage to living cells. The OET device generally comprises a planar liquid-filled structure having one or more portions which are photoconductive to convert incoming light to a change in the electric field pattern. The light patterns are dynamically generated to provide a number of manipulation structures that can manipulate single particles and cells or groups of particles/cells. The OET preferably includes a microscopic imaging means to provide feedback for the optical manipulation, such as detecting position and characteristics wherein the light patterns are modulated accordingly.

摘要： A 1×N2 wavelength selective switch (WSS) configuration in which switch elements are configured in a way that enables the input or output fibers to be arranged in a two-dimensional (2D) array. By employing 2D arrays of input/output channels, the channel count is increased from N to N2 for wavelength selective switches. In one embodiment, in which the components are arranged as a 2-f imaging system, a one-dimensional (1D) array of mirrors is configured such that each mirror has a dual scanning axis (i.e., each mirror can be scanned in X and Y directions). In another embodiment, in which the components are arranged as a 4-f imaging system, two 1D arrays of mirrors are configured with orthogonal scanning directions. In both embodiments, the number of ports is increased from N to N2.

摘要： The periodic array of photodiodes are disposed in a passive optical waveguide electrically coupled in series with each other by microwave transmission line. The collective array of photodiodes coupled to the optical waveguide and microwave transmission line results in an increased bandwidth-efficiency product for the photodetector array as compared to any single photodetector within the array. High optical-to-electrical conversion efficiencies near unity are achieved at frequencies as high as several hundred GHz. High efficiencies are achieved by matching the group velocity of the optical waves within the optical waveguide with the group velocity of electrical signals being transmitted in the microwave transmission line by appropriate selection of the capacitance of each of the photodiodes. Power saturation is improved by decreasing the optical density within the active layer of the photodiodes. Optical coupling efficiencies from optical fibers into and from the optical waveguide are further improved by enlarging the optical mode size in the optical waveguide.

摘要： A system and method of optically routing wavelength channels from within a plurality of optical inputs to any of a plurality of optical outputs. An optical wavelength-selective cross connect (WSXC) switch is described with a first stage of wavelength division multiplexing (WDM) routers which support an optical input and a plurality of optical outputs, which are interconnected to a second stage of WDM routers having a plurality of optical inputs and an optical output. The wavelength channel is routed in two stages from one of the input stage routers to an output stage router for output. It should be appreciated that the WSXC switch of the invention can be utilized for passing optical signals in either direction. In a preferred implementation integrated circuit router chips are stacked into cubes to form the routers stages which are cross coupled using a twisted butt joint to form a WSXC switch.

摘要： Disclosed is an advantageous method of making ridge-waveguide lasers. The method is a self-aligned method that does not comprise any critical alignment steps. Thus it is useful for making lasers that have a very narrow ridge waveguide. Such lasers are desirable because they can suppress lateral higher order modes.
