Abstract
A family of photorefractive polymer composites has been developed that enable high-performance device operation at a wavelength of 975 nm. 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 100 cm ⁻¹ 60% diffraction efficiency in four-wave mixing experiments, and a fast response time of 33 ms, at an irradiance of 1 W/cm².
