Abstract
A reconfigurable optical cross-connect switch includes N input ports and M output ports, where N and M are integers with a value of two or more. The switch has a set of switching stages where each switching stage includes a polarization switch to receive an input linearly polarized optical beam. One or more birefringent prism pairs associated with the polarization switch directs the input linearly polarized optical beam to any of the M output ports through control of the polarization switch.
