Abstract
The present invention provides for a polarization independent optical switch for selectively switching an optical signal from at least one input port to a preselected one of a plurality of different output ports. The optical switch operates to transmit all of the optical signal from an input port to a predetermined one of the output ports without first segmenting the optical signal into two polarizations.
