Paper Abstract

We describe on-going research to develop photorefractive polymeric materials with improved speed, material stability, and high beam coupling gain. The demonstration of significantly improved two-beam coupling is shown to mark the entry into a gain regime which enables the observation of new effects for the first time, such as beam fanning and self-pumped phase-conjugation. These effects have previously been reserved to a few thick high gain inorganic photorefractive crystals. We discuss how the large beam coupling has forced the reinterpretation of such traditional characterization techniques such as the grating translation method for the determination of the spatial phase of the index grating. Our subsequent material study focuses on several compositional variations to investigate the effect that varying the chromophore and charge transporting polymer has on the photorefractive effect.
