Abstract :
The III-V bulk and multiple quantum well (MQW) semiconductor electrooptic (EO) modulators have been successfully demonstrated with high modulation bandwidths. However, one of the drawbacks is a high switching voltage. This is mainly due to small EO coefficients of III-V semiconductor materials. Quantum dot (QD) devices have been predicted to be superior to bulk or MQW devices in optical nonlinearities and enhanced EO effects.
