Abstract
Photopolymers, in the context of this chapter, are systems of organic molecules that rely on photoinitiated polymerization to record volume phase holograms. Characteristics such as good light sensitivity, real-time image development, large dynamic range, good optical properties, format flexibility, good image stability, and relatively low cost make photopolymers one of the most promising materials for write-once, read-many (WORM) holographic data storage applications. We first present a brief description of the chemistry of photopolymers. This is followed by a discussion of photopolymer properties that are particularly relevant to the requirements of recording holograms for data storage. The intent of this chapter is to provide the nonspecialist with an appreciation of the possibilities and promise offered by photopolymers as candidate materials for holographic data storage, and to highlight areas where additional material development is desired. Readers interested in other aspects of photopolymers in holography can consult reviews by Lessard and Manivannan [1], Lougnot [2], and Colburn [3].
