A family of photorefractive polymer composites has been developed that enable high-performance device operation at a wavelength of . This constitutes a major extension into the near-infrared spectral region for the operation of all-organic photorefractive devices. Utilizing our photorefractive materials, we demonstrate large net two-beam coupling gain of more than , 60% diffraction efficiency in four-wave mixing experiments, and a fast response time of , at an irradiance of .
