| 摘 要： | 分析了不同空气孔形状的光子晶体受位置和半径微扰对于透射的影响,包括圆形,方形与椭圆形.仿真结果发现及形状相同微扰程度下,通过比较透射平坦带宽部分的分析得到透射率对位置微扰更加敏感.慢光区域正方形空气孔对于位置微扰表现较好,圆形空气孔对于半径微扰更稳健.由于不同形状的空气孔光子晶体波导结构有各自的优势,因此研究微扰对透射...

| Abstract: | The impact of positional and radial disorders on the transmission spectrum of photonic crystal waveguides with different shapes of air-holes, including circular, square and elliptic were numerically investigated. It was found that the disorder affects the anti-crossing point greatest.The flat transmission spectrum becomes narrower as disorder increasing. The transmission property performs more sensitive on the air-holes positions than radii. The square air-holes are more robust against the positional disorder. The circular air-holes are more robust alainst the radial disorder. These results provide important theoretical instructions on the imperfection during the manufacture possess in the PCWs experiment. |
