Frustrated total internal reflection optical switch using waveguides and method of operation

摘要

An optical switch for processing an optical signal includes a refractive material and an input waveguide formed in the refractive material that is operable to receive an optical signal. First and second output waveguides are also formed in the refractive material. A switchplate is coupled to the refractive material and has a first position spaced apart from the input waveguide and a second position in proximal contact with the input waveguide. When the switchplate is placed in the first position, the input waveguide totally internally reflects the optical signal toward the first output waveguide. When the switchplate is placed in the second position, the switchplate frustrates the total internal reflection of the optical signal such that the second output waveguide receives the optical signal.
