Paper Abstract

A partially asymmetric quantum-well Fabry Perot uses unequal partial reflections from front and back interfaces and balances destructive interference upon reflection by relying on intrinsic absorption in the quantum wells. The antireflection condition produces large modulation contrast ratios for reflected beams, while the partial reflections simultaneously allow transmission through the device. When the device is operated as a holographic optical element by incorporating a photorefractive quantum well structure in the Fabry Perot, output diffraction efficiencies can approach 100%. These holographic devices are optically addressed and electrically switched. In this paper we present theoretical calculations of the properties of partially asymmetric Fabry-Perot quantum wells.
