GaAs optoelectronic neuron arrays

Not Accessible

Your library or personal account may give you access

Abstract

A simple optoelectronic circuit integrated monolithically in GaAs to implement sigmoidal neuron responses is presented. The circuit integrates a light-emitting diode with one or two transistors and one or two photodetectors. The design considerations for building arrays with densities of up to 104 cm−2 are discussed.
