Abstract : Spatially variant interconnects show great potential in the fields of optical computing and optical communications. Two dimensional forms of these interconnects offer even more power over their stacked one dimensional or wrap around counterparts. Several ingenious classical optical approaches exist to implement these complicated optical routing patterns, however all exhibit scalability and efficiency problems which make them unsuitable for use in a practical connection scheme. The interconnects we describe are recorded in dichromated gelatin, utilising its high space band width product, efficiency and good uniformity. They offer point to point on-axis interconnection with a high packaging density (compatible with current demonstration optical circuits) and have been generated for a range of wavelengths. Furthermore, we have coupled several interconnection stages together (in both transmission and reflection modes of operation) to demonstrate prototype networks.
