Abstract
An optical switch array in which a plurality of input waveguides is coupled to a plurality of output waveguides. All but one of the output waveguides is coupled to each of the input waveguides by a switching element such as a 1×2 switch. A combining mechanism couples all the input waveguides to each of the output waveguides. In one preferred embodiment, one of the input waveguides continues directly into the output waveguide that is not coupled to input waveguides by switching elements, and each combining mechanism includes, for each of the other input waveguides, a coupling element such as a y-junction combiner. The switching elements are connected to the corresponding combining mechanisms by intermediate waveguides. Intermediate waveguides intersect input waveguides as required to allow the array to be fabricated as a planar integrated device.
