Improved stability of photorefractive polymer composites by use of eutectic mixture of EO chromophores

Summary form only given. Recently, organic photorefractive (PR) materials have attracted a lot of attention as recording media for photonic applications, including real-time optical processing and holographic data storage. The latest PR polymers show steady-state performance that compete and in some cases even surpass the performance of traditional inorganic materials. However, a drawback of these high-performance materials is their short shelf-life time, in particular in humid environments. Here we use an eutectic EO chromophore mixture.
