ABSTRACT:
An optical logic element includes an optical bistable npnp element for switching from a high resistance state to a low resistance state in response to electrical bias and incident light energy in which the switching time becomes shorter as the incident light energy becomes larger. The elements emit light in the low resistance on state. The optical logic element is designed for analog threshold processing of light energy. A plurality of optical bistable elements connected in parallel differentially threshold process incident light energy. An opto-electronic conversion apparatus includes linear arrays of light emitting elements, a two-dimensional array of optical memories, i.e., optical bistable elements, and linear light receiving element arrays arranged transverse to the light emitting element arrays, all integrated with each other. Corresponding light emitting elements, optical memories, and light receiving elements permit arbitrary transfers of signals. Periodic refresh light pulses maintain each optical memory in an established state.
