光聚合物因其高灵敏度和高折射率对比度而成为高密度全息数据存储的有吸引力的候选者。我们已将几种高指数有机单体纳入高光学质量丙烯酸酯低聚物基础配方。使用反应性比、反应动力学和组分折射率作为指导，与最初的全丙烯酸酯配方相比，an增加了b倍。从这些配方制备的样品已被用于在给定体积的材料中写入和读取bb200个高质量全息图。这是光聚合介质首次成功地用于复刻如此数量的全息图。利用这些树脂，开发了一种评价光聚合物作为全息介质的方案。
Photopolymers are attractive candidates for high-density holographic data storage because of their high sensitivity and refractive index contrast. We have incorporated several high-index organic monomers into high optical quality acrylate oligomer-based formulations. Using reactivity ratios, reaction kinetics, and component refractive indices as guidelines, a B-fold increase in an has been achieved compared to an initial all-acrylate formulation. Samples prepared from these formulations have been used to write and read >200 high-quality holograms in a given volume of material. This is the first time a photopolymeric medium has successfully been used to multiplex this number of holograms. Using these resins, a protocol for the evaluation of photopolymers as holographic media has been developed.
