  • Patent number: 6519382
    Abstract: 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.
    Type: Grant

  • Patent number: 6516107
    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.

  • Patent number: 6453084
    Abstract: A system for processing an optical signal includes a reflector that reflects an input optical signal to a selected one of a number of output waveguides and reflects a reference optical signal associated with the input optical signal. A detector detects a position coordinate of the reference optical signal. A memory coupled to the detector stores an expected position coordinate for the reference optical signal. A controller coupled to the memory generates a control signal based upon the position coordinate detected by the detector and the expected position coordinate stored in the memory. An actuator coupled to the reflector positions the reflector in response to the control signal.

  • Patent number: 6438283
    Abstract: An optical switch for processing an optical signal includes a refractive material having a first surface, a second surface, and a third surface. A first embodiment of the optical switch includes a lens having a planar surface that is coupled to the third surface of the refractive material, and a convex surface. A second embodiment of the optical switch includes a collimating lens, a first decollimating lens, and a second decollimating lens. The optical switch further includes a switchplate coupled to the second surface of the refractive material. The switchplate has a first position spaced apart from the second surface and a second position in proximal contact with the second surface.
