Abstract:
An optical switch, comprising:an input member operable to support an input waveguide having a reflective surface and operable to receive an optical signal; a reflective output member coupled to the input member and operable to support a first output waveguide and a return loop waveguide that is coupled to the input waveguide and the first output waveguide; and a transmissive output member operable to support a second output waveguide, the transmissive output member having a first position spaced apart from the input member such that the reflective surface of the input waveguide totally internally reflects the optical signal toward the return loop waveguide for communication to the first output waveguide, and a second position in proximal contact with the input member such that the second output waveguide frustrates the total internal reflection of the optical signal and receives the optical signal.
