摘要
从多光束干涉基本原理出发,对激光全息制作光子晶体的普遍规律和影响因素进行了研究。进一步通过Matlab软件进行数值仿真,以三角晶格为例系统研究了光束的不同偏振类型组合对光子晶体微结构的影响。利用三角晶格光束配置的对称性,在等光强条件下研究了三组共10种不同光束偏振组合对微结构的光强极大、极小值和对比度的影响,进一步总结了激光偏振改变时光子晶体微结构的变化规律,并得到了实现最佳对比度三角晶格微结构的偏振组合。
Based on the multiple beam interference principle, the common rules and influence factors in holographic fabrication of photonic crystals are studied. Furthermore, taking triangular lattice as an example, the polarization combinations influence on photonie crystal microstructures is studied by Matlab simulations. Using symmetry of the beam configuration of triangular lattice, the influence of polarization combinations on the intensity maximum, minimum value and contrast under the equal intensity condition is studied by dividing ten kinds of polarization combinations into three groups. The influence rules of polarization change on the photonie crystal microstruetures are further summarized. Finally, a set of optimal polarization combination for triangular lattice with optimal contrast is obtained.
