Abstract
- We report a novel approach to the design of normal incidence multiple quantum well light modulators. The quantum confined Stark effect is utilized to tune the light polarization rotation and phase retardation created by a thermally induced in-plane anisotropic strain. An exceedingly high contrast ratio of 5000:1 is demonstrated for a normally-on device at room temperature. >
