ABSTRACT:
An optical switch includes a polarization splitter/combiner that is made of a material that changes its refractive index in response to voltage. The polarization splitter divides an input beam into a first polarized component and a second polarized component. Each of the first and second polarized components is fed into a first polarization-sensitive deflector and a second polarization-sensitive deflector, each of which deflects a light beam by a predetermined angle. A plurality of polarization combining systems are positioned to receive a deflected first component and a deflected second component and combine the first and the second deflected components into an output beam propagating through an output fiber.
