title: Programmable optical threshold logic implementation with an optoelectronic circuit.
abstract: We demonstrate optical binary threshold logic by using an optoelectronic circuit. This threshold gate is in itself a logical complete set owing to the availability of both positive and negative weights and threshold. Furthermore, the weights and the threshold are optically addressed, thereby providing real-time operation. Experimental results demonstrate AND, OR, and MAJORITY functions and three other arbitrary logic functions for three input signals with a single gate. Applications in neural computing and two-dimensional parallel logic processing are discussed.
