Abstract : Electro-absorption and electro-refraction properties of strained multiple quantum-well structures (QW) in In(x)Ga(1-x)As/GaAs were investigated for spatial modulation applications. A new technique that will allow us to obtain large number of quantum well periods and large depth of modulation has been developed. Optical-optical interaction of a modulator-detector diode pair made form such QW structure had been demonstrated. Optimization of QW structure design has been investigated. Keywords include: III-V Compound Semiconductors, Electro-absorption, Electro-refraction, Quantum Wells, Spatial Light Modulation.
