Abstract
Photorefractive polymers have improved considerably in recent years.1 Due to their higher processing capabilities compared with inorganic photorefractive crystals and their high efficiency and sensitivity they appear as promising new materials for photonic applications. Due to high refractive index modulations that can be achieved2 in DMNPAA:FVK:ECZ:TNP guest/host photorefractive polymers (Δn = 7 × 10−3), we recently demonstrated2 with these polymers a variety of optical applications including holographic storage and dynamic holographic interferometry3 with low-power laser diodes in a four-wave mixing geometry.
