Photopolymer materials have received a great deal of attention because they are inexpensive, self-processing materials that are extremely versatile, offering many advantages over more traditional materials. To achieve their full potential, there is significant value in understanding the photophysical and photochemical processes taking place within such materials. This paper includes a brief review of recent attempts to more fully understand what is needed to optimize the performance of photopolymer materials for Holographic Data Storage (HDS) and Self-Written Waveguides (SWWs) applications. Specifically, we aim to discuss the evolution of our understanding of what takes place inside these materials and what happens during photopolymerization process, with the objective of further improving the performance of such materials. Starting with a review of the photosensitizer absorptivity, a dye model combining the associated electromagnetics and photochemical kinetics is presented. Thereafter, the optimization of photopolymer materials for HDS and SWWs applications is reviewed. It is clear that many promising materials are being developed for the next generation optical applications media.
光聚合物材料因其价格低廉、可自加工且用途极为广泛，相对于更传统的材料具有诸多优势，故而受到了广泛关注。为充分发挥其潜力，深入了解此类材料内部发生的光物理和光化学过程具有重要价值。本文简要回顾了近期为更全面理解优化用于全息数据存储（HDS）和自写入波导（SWWs）应用的光聚合物材料性能所需条件所做的尝试。具体而言，我们旨在探讨对这些材料内部发生的情况以及光聚合过程中发生的情况的理解演变，以期进一步提高此类材料的性能。首先回顾光敏剂吸收率，接着提出一个结合相关电磁学和光化学动力学的染料模型。此后，对用于HDS和SWWs应用的光聚合物材料的优化进行了综述。显然，许多有前景的材料正在为下一代光学应用介质而研发。
