Abstract
An optoelectronic memory cell was constructed from two photoconducting (PC) and two electroluminescent (EL) devices. PC and EL devices were prepared by vacuum evaporation. This optoelectronic memory cell was supplied with a sinusoidal voltage. The input signal was in the shape of rectangular light pulses illuminating the PC device. The output signal was in the form of the light emitted from the electroluminescent device. Applied PC and EL devices within the optoelectronic memory cell ought to perform the determined condition, namely the optical feedback between them must exist. A value of the feedback coefficient ought to be such as to perform the bi-stable circuit operation.
