Abstract

An input beam of radiation (100) incident upon a polarization independent optical switch is resolved into two component beams (110 and 120) having orthogonal linear polarizations. The component beams both pass through a polarization rotator (20), which rotator transmits the component beams without attenuation. The two component beams are then recombined to provide the output beam of radiation (130 or 102) which emerges from the device. When the polarization rotator cell is configured to rotate the polarization of the component beams by 0 DEG the output beam of radiation travels in a first direction (130) and when the polarization rotator is configured to rotate the polarization by 90 DEG the output beam of radiation is switched to a second direction (102). In one embodiment the polarization rotator is a liquid crystal twist cell. <IMAGE>
