Abstract: A method may include receiving, by a switching engine, an optical signal. The optical signal may carry a super-channel that includes a plurality of sub-carriers to be directed toward respective output ports. The switching engine may have a plurality of regions of pixels on which respective sub-carriers, of the plurality of sub-carriers, are incident. The method may include applying, by the switching engine, respective single beam steering gratings to first, overlapping, areas of the plurality of regions of pixels. The method may include applying, by the switching engine, one or more respective pluralities of beam steering gratings to second, overlapping areas of the plurality of regions of pixels. The method may include directing, based on the single beam steering gratings and the one or more pluralities of beam steering gratings, parts of the optical signal toward the respective output ports.

Abstract: A method may include receiving, by a switching engine, an optical signal that includes a channel. The method may include applying, by the switching engine, a first beam steering grating to direct a first portion of the channel to a first output port. The method may include applying, by the switching engine, one or more second beam steering gratings to direct at least one of a second portion of the channel to a second output port, or a third portion of the channel to a photodetector. The third portion may be approximately less, in power, than 10 percent of the channel.
