    摘要: A re-configurable optical waveguide includes an electro-optic substrate and plurality of electrodes above substrate. Electrodes are forming photonic crystal waveguide with photonic crystal periodic structure which has a slab optical waveguide on the top surface of a substrate and also has refractive index variation areas due to electro-optical effect with a different refractive index from that of the core layer of the slab optical waveguide arranged in a lattice array shape at part of the slab optical waveguide. In this case, the refractive index variation areas are formed of the same material as the material constituting the core layer of the slab optical waveguide. The refractive index variation areas are arranged in the lattice array shape on both the sides of an optical waveguide area, where light is propagated. The refractive index of the core layers of the refractive index variation areas is larger than that of the core layer of an area of the refractive index variation area. A plurality of electrodes are placed a field emission array with structure density possibly being higher than 10+8 per square centimeter. Groups of the structures are united in pixels with size a equal to the waveguide's width. Different arrays of pixels form variable shapes and, appropriately, variable waveguides. Thus light propagates in the different directions according the waveguide which is formed. Such a waveguide allows implementation of different optical functions simply by changing the arrangement of the patterns. Arrangement of the patterns is controlled with integrated transistor structure, and with a coupled control circuit.

    摘要: The invention is directed to techniques for inspecting a circuit board having a surface that includes at least one circuit board component. The apparatus includes a base, and a set of reflective members that includes at least one reflective member. Each reflective member of the set of reflective members is (i) supported by the base and (ii) movable relative to the base to enable that reflective member to move to an angle that reflects light from a respective portion of a circuit board component (e.g., a solder region between the component and the circuit board) in a direction away from the surface of the circuit board when the base rests on the surface of the circuit board. Since the base can rest on the surface of the circuit board, a technician does not need to hold the apparatus.

    摘要: An improved rework nozzle includes an open housing which when lowered onto the surface of a board forms a closed cavity. The housing includes venting means which expend air that is input to the cavity, thereby using flow through concepts to maintain a uniform temperature in the cavity. The housing also positioning mechanisms for both aligning a the housing and a captive integrated circuit to a desired footprint on the circuit board, and for limiting movement of the integrated circuit during rework.
