An optical switching fabric with an optical to electrical converter in the output plane. The optical switching fabric has an input plane with at least one input. The input plane provides at least a first optical signal (e.g., a first set of optical signals). The optical switching fabric has an output plane. The optical switching fabric has an interconnection mechanism for receiving the first set of optical signals and directing each received optical signal to a predetermined location in the output plane. The output plane has at least one optical to electrical converter (e.g., a plurality of optical to electrical converters) for receiving the directed optical signals and responsive thereto for generating a set of corresponding electronic output signals.

An optical switch has a plurality of input ports and a plurality of output ports. The optical switch features a fan-out fan-in architecture has a fan-out stage, a fan-in stage, and a coupling mechanism. The fan-out stage is coupled to the plurality of input ports and has a first orientation. The fan-in stage is coupled to the plurality of output ports and has a second orientation. The coupling mechanism optically couples the fan-out stage with the fan-in stage and maintains a predetermined relationship between the first orientation of the fan-out stage and the second orientation of the fan-in stage.

Optical switch with a geometry based on perpendicularly-oriented planar lightwave circuit switches

A light source for generating and coupling light from a first wavelength into an optical fiber. The light source includes an output laser having a first optical cavity that includes a bottom mirror located outside of the optical fiber, and a top mirror that includes a reflector located within the optical fiber. An active region between the top and bottom mirrors generates light of the first wavelength, preferably through optical pumping at a second wavelength. The reflector is preferably a Bragg reflector and may include a mechanism for altering the wavelength of the light reflected thereby as well as the distance between the top and bottom mirrors. The pumping light is preferably generated by a pumping laser that includes a second electrically pumped optical cavity having a top mirror that is electrically connected to the bottom mirror of the first optical cavity.
