Abstract

The results of a successful demonstration of the selection module of an optoelectronic parallel-processing database filter is presented. The module utilizes 4 × 4 arrays of and and xor logic gates that respectively perform the functions of reducing the data fields and determining a match between the input data and a selection argument. The logic arrays were fabricated with InGaP/GaAs heterojunction phototransistors that drive vertical-cavity surface-emitting lasers (VCSEL’s). The VCSEL’s provide the free-space optical interconnection between stages. The design of the system and the optical power budget are discussed.
