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.
