Hybrid optoelectronic implementations combine the strength of optics in communications with that of electronics in computation. The authors describe a multilayer feedforward neural network implementation using neurons (computational elements) and synapses (connections between neurons) fabricated on an integrated circuit. Each synapse contains a photodetector thus allowing weights governing the connections to be accessed holographically from an optical disk. The authors have written holograms onto 5 1/4 inch reflective disks using a prototype Sony system.
