Photopolymer is an attractive holographic material for many applications such as data storage, micro-optical elements, optical connecting, display application, and other information processing. In this study, the diffraction grating in novel photopolymer system prepared with photoreactive polymer as a binder was fabricated by optical interference method. Specroscopic study revealed the chemical bond between the polymer binder and newly formed polymer in part. The dynamic behaviors of diffraction efficiency with the exposure intensity of pump beam were studied in detail. The temperature dependence of the diffraction efficiency was also investigated to evaluate the thermal stability of newly formed diffraction gratings. |
