ABSTRACT:
An optical switch (10) in accordance with the present invention includes a first PBS (101), a second PBS (104), two reflective elements (102, 105) and two liquid crystal elements (103, 106). The first PBS splits input light into two polarized beams, said two beams being orthogonally polarized with respect to each other. The two beams each respectively pass through a different liquid crystal element and a reflective element. The polarization state of the passed beams can be controlled by the electrified or unelectrified state of the liquid crystal elements. The two beams are combined into one output beam by the second PBS, and are outputted from a selected output port (13, 14) depending on the state of electrification of the liquid crystal elements.
