Abstract :
A GaAs/AlGaAs optical synaptic interconnection device for neural networks is reported. It consists of a light-emitting-diode array, an interconnection matrix, and a photodiode array, which are integrated in a hybrid-layered structure on a GaAs substrate. The device structure and characteristics are reported. The fabricated device can simulate a 32-neuron system. The experimental results for a Hopfield associative memory with three stored vectors are described.<>
