摘要：

We present an optical logic device which demonstrates hardlimiting of outputs and which has the potential for large fan-out and fast response. It consists of a waveguide modulator made from GaAs/AlGaAs multiple-quantum-well material and a phototransistor, and exhibits a contrast in excess of 20.
