Abstract
An optical switch includes an input member, a reflective output member coupled to the input member, and a transmissive output member. The input member supports a plurality of input waveguides, each input waveguide having a reflective surface and operable to receive a corresponding optical signal. The reflective output member supports a plurality of first output waveguides, each first output waveguide coupled to a corresponding input waveguide. The transmissive output member supports a plurality of second output waveguides and has a first position spaced apart from the input member such that the reflective surface of each input waveguide totally internally reflects a corresponding optical signal to a corresponding one of the first output waveguides, and a second position in proximal contact with the input member such that each second output waveguide frustrates the total internal reflection of a corresponding input waveguide and receives a corresponding optical signal.
