    摘要： An optical fiber switch in accordance with an embodiment of the present invention includes a first plurality of ports, a second plurality of ports, a first plurality of mirrors disposed on a first surface, and a second plurality of mirrors disposed on a second surface. Each one of the first plurality of mirrors is individually controllable to direct light output from a corresponding one of the first plurality of ports to any one of the second plurality of mirrors. Each one of the second plurality of mirrors is individually controllable to direct to a corresponding one of the second plurality of ports light incident on it from any one of the first plurality of mirrors. Advantageously, optical fiber switches in accordance with embodiments of the present invention may couple more than a thousand input ports to more than a thousand output ports with an insertion loss of less than about 3 decibels.

    摘要： An optical switching fabric enables an optical signal entering the device on any one of multiple input ports to be directed to any one of multiple output ports. The present optical switching fabrics include sensing and monitoring devices that permit precise initial calibration and continuous switch connection status monitoring and control. Light entering the switching fabric on an input port is reflected by one of a first set of individually controllable mirrors to one of a second set of individually controllable mirrors and then to a corresponding output port. The switching fabrics include control lasers and position sensing devices which provide output signals corresponding to the orientations of the mirrors. In addition, a subset of the input ports and output ports can be attached to monitor light sources and detectors for recalibration and control. Further, sensors for detecting the intensity of input signals, of signals that have been reflected by a mirror in the first set and by a mirror in the second set, and of signals backscattered from the output ports may be included.
