Abstract

An optical phase shifter with current injection has been demonstrated in a GaAs/AlGaAs multiple quantum well (MQW) single mode waveguide. Phase shifts at different wavelengths have been measured and compared with the theory in L. Banyai and S. W. Koch, Z. Physik B 63, 283 (1986). A 3π phase shift has been achieved in a 400-μm-long waveguide with almost no material absorption.
