Abstract
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.
