Abstract
Controllable optical switches in response to feedback signals from optical position sensors that measure switch orientations. The optical position sensors may include local sensors that monitor and measure orientations of individual switches and global sensors that monitor and measure overall alignment of signal beams. Such switches may be used to form non-blocking switching arrays.
