Abstract
An improved design for optically addressed multiple-quantum-well spatial light modulators is reported. These integrated AlGaAs modulators are of high optical quality and are simple to fabricate. They exhibit excellent performance characteristics such as 10:1 reflection contrast ratio, 1.5% diffraction efficiency, 7-μm spatial resolution, and illumination sensitivity less than Additionally, a new mode of operation is reported that dramatically improves the optical response of these devices at low frequencies. A new physical model is proposed that accurately describes the modulation process.
