摘要: | Photopolymers have been applied widely in optical devices for communications. displays. bio-sensing. and data storage. The advantages of this material are easy to synthesize, high refractive index change. high sensitivity and good optical quality. Recently, we have investigated on the syntheses and analysis of 9,10-PhenaiithreneQuinone doped Poly(Methyl MethAcrylate) (PQ:PMMA) photopolymer. This material can be fabricated with large dimensions and with thickness in the range of several-centimeters. Experiments show that the material shrinkage is negligible after optical exposure such that our doped photopolymer is attractive for volume holographic applications. However. comparing with other photopolymers, our PQ:PMMA material has a drawback of lower sensitivity (similar to10 mW/cm(2)). In this presentation. we demonstrate that by adding organo-metallic compound (Zinc MethylAcrylate. ZnMA) into the PQ:PMMA photopolymer. we succeeded in reducing response time and increasing holographic diffraction efficiency of the material. We report the fabrication and experimental investigation of dye-doped photopolymer. and discuss their application for data storage. |
