Abstract

The operation of a matrix-addressed GaAs quantum well modulator utilising the quantum confined Stark effect is described. The performance of the array was determined by limitations imposed by the electrical circuit and by the uniformity of the quantum well material. Individual modulators gave a modulation depth of 8.9 dB at the optimum working wavelength of 837 nm. In an array configuration the modulation depth dropped to 6.2 dB at 838.1 nm.
