摘要： Methods of calibrating and operating optical switches as well as optical switches in which the orientations of mirrors are measured and controlled using control light beams and position sensing detectors are described. The present invention may provide high resolution control of a plurality of mirrors in an optical switch and thus allow the optical switch to cross-connect a large number of input and output ports with a low insertion loss.

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： A method of controllably attenuating a beam of light coupled into a port includes directing the beam of light against a mirror, and controlling an orientation of the mirror such that a predetermined fraction of the beam of light is coupled into the port. The predetermined fraction is less than a maximum fraction corresponding to optimal coupling of the beam of light into the port. The method may be implemented with a variable optical attenuator including a first port, a second port, a mirror located to direct light output by the first port to the second port, and a controller coupled to the mirror to align it such that the predetermined fraction of light is coupled into the second port. The method may also be implemented with an optical switch.
