Holographic Interconnect Components for Optical Processing Systems

Both computer-generated and optically-recorded holograms play important roles in the current generation of optical computing demonstrator systems. This paper reviews the various types of holographic interconnect components that have been used in a series of optical parallel digital processing experiments at Heriot-Watt University. Both high-level and low-level space-invariant fan-out elements are covered, along with components for space-variant interconnect systems.
