The presented compact architecture overcomes this problem but raises several others, which are the additional interconnects between the separated inputs and outputs of a switch and the backreflection of light inside the architecture. Additional interconnects can be avoided by the interleaved organization of the switching arrays, or a mix of inputs and outputs. Different interconnect organization schemes are analyzed and evaluated. The avoidance of backreflection of light is discussed.enhypercube networksmultiplexingoptical information processingoptical interconnectionsoptical switchescompact interconnection networksphotonicsmultistage interconnection networksdesign parameterscompact architectureoptical switch interconnectslight backreflectionswitching arraysinterconnect organization schemesoptical computing621535journal article
