Paper Abstract

Several novel photorefractive polymers based on the charge transfer properties in photosynthetic model compounds were synthesized. These polymers contain a prophyrin moiety, a second order nonlinear optical chromophore covalently linked to a polyimide backbone. High thermal stability of the second order nonlinear effect were observed at elevated temperatures. An asymmetric optical energy exchange was detected in two beam coupling experiments, indicating the photorefractive nature of the polymers. Large optical gains were deduced at zero-external electric filed (20 cm-1).
