Abstract

The waveguide electro-optic modulator based on the quantum confined Stark effect (QCSE) in quantum wells (QWs) is very important.1 The exciton-energy Stark shift ΔE of each carrier is proportional to its effective mass m. The mass difference between heavy hole (HH) and light hole (LH) brings about the polarization dependence between TE and TM modes.
