Abstract

Optical logic elements, especially in the form of 2-D arrays, can possibly be applied to massively parallel signal processing. GaAs/AlGaAs multiple-quantum-well etralons have previously shown optical bistability¹ and various types of logic-gate operation² at room temperature. Most of these experiments have used a dye laser, which is large in size and expensive. One attractive feature of these devices is that a GaAs/AlGaAs diode laser can be used as a light source making the total system more practical. The present paper demonstrates a stable optical NOR gate using two diode lasers.
