非水溶性光致聚合物光子晶体的研制

报道了一种新型的利用激光全息技术制作光子晶体的记录材料,即自制的非水溶性光致聚合物.用绿光作为光源对材料性能参量做简单测试,经测试其衍射效率可达85%,在波长为514.5 nm处拥有较高的吸收率,且该材料的后处理过程简单,只需热烘.利用Matlab简单模拟全息法制作光子晶体的过程,经模拟得到干涉的光束越多,光子晶体的晶格结构越复杂.设计了制作二维、三维光子晶体的实验光路,分光元件分别为掩模板和去顶棱镜.实验结果表明,利用非水溶性光致聚合物可制作大面积、大体积、耐高温和高强度的二、三维光子晶体,且其晶体结构与Matlab模拟的结果基本一致|利用非水溶性光致聚合物作为记录材料时,光路的搭建是影响实验结果的重要因素.

Development of Photonic Crystals Using Water-resisting Photopolymer

 A novel recording material of holographic fabrication for photonic crystal was proposed.The material is home-made water-resisting photopolymer.Using green laser as the laser source,its performance parameters were simply measured.After testing,its diffraction efficiencies could reach 85%,and its absolution is high with the wavelength of 514.5 nm.Besides,the later development is simple,only heating.Holographic fabrication of photonic crystal was also simply simulated by Matlab software.The results indicate that the more beams interfere,the more complex photonic structures of photonic crystal are.And the simple light paths for fabricating 2-D and 3-D photonic crystal were designed.The light splitting elements are a mask and a top-cut prism.The experimental results indicate 2-D and 3-D photonic crystal with large-area,bulk-mass,high temperature resistance and high-strength can be fabricated using water-resisting photopolymer.It has the same photonic structures with matlab simulation.And the setup of the path is an important factor when the material is home-made water-resisting photopolymer.
