摘要：

A multiple-quantum-well film bonded to glass has high transmittance while performing simultaneously as a reflection asymmetric Fabry-Perot electro-optic modulator. When the multiple-quantum-well structure is made semi-insulating through proton implantation, the device becomes photorefractive and sensitive to dynamic space-charge grating formation. We demonstrate a photorefractive Al0.1Ga0.9As/GaAs multiple-quantum-well asymmetric Fabry-Perot device that has diffraction orders in both transmission and reflection. The reflection diffraction efficiency is enhanced by a favorable front/back reflectivity ratio for the incident glass-first interface geometry. We obtain output diffraction efficiencies of 1.3% in reflection and 0.7% in transmission, corresponding to input diffraction efficiencies of 0.15% in reflection and 0.22% in transmission.
