Abstract
The present invention includes a polarization independent optical interconnect device for selectively interconnecting a plurality of optical signals between a plurality of inputs and a plurality of outputs. The present invention may provide advantages typically associated with conventional polarization based switches, including terabit per second data rates and high speed switching, to facilitate use in fiber optic networks. Moreover, the switch of this invention is polarization independent, and therefore, may route either polarized or unpolarized light. Since both the input and output light may be unpolarized, the switch of this invention may have a high light efficiency (i.e. no losses associated with an input polarizer) and minimal insertion losses as compared to typical polarization based switches.
