  • Patent number: 6771851
    Abstract: A fast method of switching optical signals using micro-mirror structures and control. The method selects an optical path for a micro-mirror device, the mirror device being coupled to a torsion bar device. The micro-mirror device is moved or pivoted about a torsion bar device, the micro-mirror device being operated about the torsion bar device through an operating range. The micro-mirror device is subjected to a mechanical force from the torsion bar and being subjected an electro-static force applied to the micro-mirror device. The method positions the micro-mirror device to a selected switching location within the operating range a selected region within a predetermined time. The micro-mirror device is controlled during a portion of time during the moving by receiving position signals periodically at a predetermined frequency from a sensing device coupled to the micro-mirror device.

  • Patent number: 6456753
    Abstract: An apparatus for switching one of a plurality of optical signals from a plurality of optical fibers. The apparatus has an input fiber bundle housing comprising an outer side and an inner side. The input fiber bundle housing has a plurality of sites oriented in a spatial manner on the outer side for coupling to a plurality of input optical fibers. Each of the input optical fibers is capable of transmitting an optical signal. The apparatus also has a first mirror array disposed facing the inner side of the input fiber bundle housing. The first mirror array includes a plurality of mirrors. Each of the mirrors corresponds to one of the sites on the outer side of the input fiber bundle housing. A second mirror array is disposed facing the first mirror array. The second mirror array is also disposed around a periphery of the input fiber bundle.
