Paper Abstract

Photo-induced cross-linking polymers offer excellent properties, such as ease of handling, low cost, and real-time recording, for the application of holography and nonlinear optics. A vinyl polymer, namely, polyvinyl alcohol (PVA), has been chosen as a host matrix and is employed for holographic recording and nonlinear optics. Significant results of our experimental investigations on recording media fabricated by doping PVA with azo dyes and rhodamine 6G for real-time holographic recording and nonlinear optics are reported. The evaluation of third-order nonlinearities of azo dye/PVA systems and the characteristics of chrysoidine/PVA as a nonlinear waveguide are presented. Also, degenerate four-wave mixing experiments using a novel geometry have been carried out in rhodamine 6G/PVA films.
