摘要:

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 B63, 283 (1986). A 3&pgr; phase shift has been achieved in a 400‐&mgr;m‐long waveguide with almost no material absorption.
