Abstract
An optical switching apparatus comprises: input ports receiving respective input optical waves, each coupled to a respective beam-forming structure comprising: an input optical waveguide, an optical power distributor to distribute optical power from a mode of the optical waveguide over the respective spatial region, and a spatially distributed phase shifter to apply different transmission optical phase shifts over different portions of the respective spatial region, where the transmission optical phase shifts determine the selected transmission angle; and output ports providing respective output optical waves, each coupled to a respective beam-receiving structure comprising: a spatially distributed phase shifter to apply different reception optical phase shifts over different portions of the respective spatial region, where the reception optical phase shifts determine the selected reception angle, an optical power combiner to combine optical power from different portions of the respective spatial region into a collected a mode, and an output optical waveguide.
