Abstract : Photorefractive quantum well structures that use Fabry Perot interference effects to enhance reflected diffraction were investigated numerically and experimentally. Hybrid transmission/reflection and fully asymmetric Fabry Perot transverse field geometry and fully asymmetric Fabry Perot longitudinal field geometry devices were studied. Diffraction was significantly enhanced by the Fabry Perot resonance. The largest output diffraction efficiency of nearly 200% was achieved in a low temperature grown AlAs barrier multiple quantum well.
