摘要：

A novel optically addressed normal incidence multiple quantum well light modulator based on polarization rotation has been demonstrated for the first time. This modulator employs the anisotropic excitonic absorption created by a thermally induced in-plane uniaxial strain in a multiple quantum well structure to achieve rotations as large as +/- 25-degrees. An exceedingly high contrast ratio of 330:1 has been measured in this device.
