摘要: 光子晶体分为简单光子晶体和复式光子晶体,激光全息法是制作复式光子晶体的重要方法之一,光束偏振在 其中扮演着重要角色。利用具有一定对称性的四光束配置干涉产生复式光子晶体,通过Matlab 编程进行数值仿真, 系统研究了不同偏振组合 (包括单光束、双光束、三光束和四光束) 对复式光子晶体元胞形状及干涉对比度的影响。 结果表明,各光束的偏振度及旋转角度均对复式光子晶体具有显著影响。在不同偏振条件下获得了一系列丰富的元 胞形状,如波浪条纹、椭圆柱、锯齿状等。此外,发现当各光束均为线偏振光时具有最佳的干涉对比度。上述研究结 果对制作特殊元胞的复式光子晶体和虚拟实验教学具有一定的理论指导意义。

Abstract: Photonic crystals (PCs) can be divided into simple PCs and compound PCs. Laser holographic interferometry is one of the important methods in the fabrication of compound PCs, in which beam polarization plays an important role. By using a four-beam configuration with certain symmetry to produce compound PCs, numerical simulations are conducted using Matlab programming to systematically study the influence of various polarization combinations (including single-beam, doublebeam, three-beam, and four-beam cases) on the unitcell shape and interference contrast of the compound PCs. The research results show that the polarization degree and rotation angle of each beam have a significant effect on the compound PCs. Under different polarization conditions, a series of rich unitcell shapes, such as wavy stripes, elliptical cylinders, zigzags, are obtained. In addition, it is found that when all the interference beams are linearly polarized, the compound PCs have the optimal contrast. The results obtained in this work have certain theoretical guidance significance for the experimental fabrication of compound PCs with various unitcell shapes, as well as the development of virtual experimental research.
