ABSTRACT:
The improved integrated optic switch includes a thin film optical waveguide on a substrate. Each of one or more input optical fibers is coupled to the waveguide and propagates a wide angle beam of light along it. Two or more light receptors, each having an optical receptor fiber, are positioned in the path(s) of the beam(s). Each receptor includes a lens for focusing each beam to a "spot" of light and a transducer for aligning the spot and the receptor fiber. Any receptor fiber may thereby receive light from any beam of light and two or more receptor fibers may simultaneously receive light from any beam.
