Optimization of polymer photorefractive materials is complicated in conventional devices because the photorefractive material usually contains both a charge photosensitizer and a nonlinear chromophore and optimization can lead to compatibility problems. In the device design presented here, the photoconductive and electrooptic components are separated, allowing them to be optimized individually. The design strategy is described and analyzed theoretically. Its limitations are pointed out and example measures of performance given.
