Abstract

Due to the random imperfections in the fabrication processes, the metallic photonic crystals might suffer from some degradation of their functionality. In the presented work, the impacts of uncertainties of the dimensions and the angle of rotations of the rods of 2D photonic crystals on their operating photonic characteristics are examined. The presented stochastic modeling is based on the Mote Carlo technique and method of frequency-dependent plane wave expansion. The research focuses on two constructions, the Metallic-Rods PCs and the Air-Holes PC, where rods and holes with both square and circular shapes are investigated. Numerical results of the stochastic analysis show that uncertainties in the dimensions of the PC on its photonic gap are more effective in case of metallic rods showing that Air-Holes PCs can be regarded as a good candidate with the least amount of photonic gap alteration resulted from design parameters’ random deviations.

二维圆形和方形金属光子晶体的随机分析

由于金属光子晶体在制备过程中存在随机缺陷，其功能可能会出现一定程度的下降。本文研究了二维光子晶体棒的尺寸和旋转角度的不确定性对其工作光子特性的影响。提出了基于蒙特卡罗技术和频率相关平面波展开方法的随机模型。研究的重点是两种结构，金属棒PC和空气孔PC，其中棒和孔有正方形和圆形的调查。随机分析的数值结果表明，在金属棒的情况下，PC的尺寸不确定性对其光子间隙的影响更大，这表明空气孔PC可以被认为是一个很好的候选者，因为设计参数的随机偏差导致的光子间隙变化最小。
