| 摘要 |
A switch device and method is disclosed that is capable of switching wavelength division multiplexed optical signals. The device comprises a switch element that may include a beam splitter, a plurality of wave plates, and a plurality of micro-electromechanical mirrors. The beam splitter is adapted to transmit light in one polarization and reflect light another polarization. The wave plates are adapted to change the polarization of the light so that the beam splitter either reflects or transmits the light. The micro-electromechanical mirrors are adapted to position the beam of light so that it is directed to a selected target.
