Abstract
A switch device and method is disclosed that is capable of switching wavelength division multiplexed optical signals. The device comprises a switch element that includes a two-dimensional micro-electromechanical mirror. The two-dimensional micro-electromechanical mirror is adapted to reflect an optical signal so that it is directed to a selected target. The switch element may also comprise a beam splitter and a plurality of wave plates. The beam splitter is adapted to transmit light in one polarization and reflect light in 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.
