Abstract
An optical switch having a fixed-position concave reflector, a fixed array of optical waveguides facing the concave reflector, said array including n number of input waveguides for transmitting the optical signal into the switch, and m number of output waveguides adapted to receive the optical signal, and a refractive element located between the reflector and the array of optical waveguides having multiple angular positions for selectively coupling one of the n number of input waveguides with one of the m number of output waveguides, the switch further including an actuator connected to the refractive element for moving the refractive element between angular positions.
