Two dimensional non-local multi-facet holographic interconnects in dichromated gelatin

Spatially variant interconnects (SVIs), such as the Perfect Shuffle, Crossover and Banyan, show great potential in the fields of optical computing and optical communications. Two dimensional forms of these interconnects offer even more power than stacked one dimensional systems, as described by Robertson et al. (1) and (2), or their wrap around counterparts, proposed by Stirk et al. (3). We present a method of fabricating such two dimensional interconnects in a volume holographic material to provide efficient, compact and modular optical interconnection schemes.
