Abstract
An optical switch includes M switch input waveguides, M being an integer greater than 1; N switch output waveguides, N being an integer greater than M; a plurality of input-waveguide cores coupled to the M switch input waveguides; a plurality of input phase shifters respectively coupled to the plurality of input-waveguide cores; a plurality of output-waveguide cores coupled to the N switch output waveguides; a plurality of output phase shifters respectively coupled to the plurality of output-waveguide cores; an input aperture at which the plurality of input-waveguide cores coupled to the M input waveguides terminate; an output aperture at which the plurality of output-waveguide cores coupled to the N output waveguides terminate; and an interference region between the input aperture and the output aperture. Light from the M switch input waveguides can be routed to switch output waveguides depending on settings of the plurality of input phase shifters and the plurality of output phase shifters.
