FRUSTRATED TOTAL INTERNAL REFLECTION SWITCH USING WAVEGUIDESAND METHOD OF OPERATION

摘要

An optical switch for processing an optical signal includes an input waveguide having a reflective surface, a first output waveguide coupled to the input waveguide, and a second output waveguide. The second output waveguide has a first position spaced apart from the reflective surface of the input waveguide such that the reflective surface totally internally reflects an optical signal toward the first output waveguide. The second output waveguide has a second position in proximal contact with the reflective surface to frustrate the total internal reflection of the optical signal such that the second output waveguide receives the optical signal.
