Abstract

Planar optical technology offers a promising compact and robust approach for performing complex optical interconnects for silicon VLSI and WSI circuits. A transparent parallel sided medium is mounted over the circuit using solder bump mounts. Arrays of reflection modulators or surface emitting laser diodes are imaged obliquely via multiple reflections within the interconnect substrate and via reflection holographic lenslets, routing elements, microprisms and microlenses to arrays of detectors. Crossover and perfect shuffle interconnect patterns are important for switching systems and already planar optical crossover interconnects using microprisms have been demonstrated. The authors describe the design and demonstration of holographic elements for performing two dimensional folded perfect shuffles in a planar optical configuration. Optical demonstrations of the perfect shuffle have used bulk lenses prisms but of particular relevance here and the demonstrations using arrays of 2×2 lenses each of which both magnifies the original image and creates 4 overlapping copies of it. Such arrays of lenslets can be recorded holographically and will perform the same operation.
