Study of the holographic storage characteristics of a green light sensitive photopolymer

Keywords： photopolymer , diffraction efficiency , holographic data storage , angular multiplexing

报道了一种对绿光敏感的以丙烯酰胺为单体的光致聚合物,该光聚物由单体、光引发剂、共引发剂和成膜物组成.可以得到材料的最大衍射效率为55%.将光聚物用不同温度进行烘烤加热,可以看到材料的折射率调制度会增加.使用角度复用技术在光聚物中存储10幅全息图,说明所研究材料有希望应用于大容量体全息存储.

Green light sensitive acrylamide- based photopolymer system was prepared. The photosensitive medium is composed of monomer, photoinitiator, coinitiator and polymeric film- forming binder. Diffraction efficiency of the photopolymer as high as 55% could be obtained. The photo polymer were baked under different temperature. It is found that the refractive modulation increases as the baking temperature increases. Ten holograms can be stored in this medium using angle multi- plexing technology. It is promising of our material for high- density volume data storage.
