Abstract

The quantum confined Stark effect (QCSE) in semiconductor quantum well (QW) structures is attractive as it gives large change in optical constants and makes efficient optical modulation possible. However, QCSE depends on polarization of the incident guided optical wave (namely, TE or TM), which is a significant problem for applications. This is mainly due to the mass difference between heavy and light holes as described in the following section.
