Abstract

We report a novel approach to normal incidence multiple quantum well light modulators. The quantum-confined Stark effect is utilized to tune the polarization rotation and phase retardation created by a thermally induced in-plane anisotropic strain. An exceedingly high contrast ratio of 4800:1 is demonstrated for a normally-on device at room temperature.
