二元复合缺陷对一维光子晶体光学特性的影响

利用传输矩阵法对二元复合缺陷光子晶体的光学特性进行了研究，重点讨论了光子晶体由二元复合缺陷结构过渡到复合光子晶体结构的过程及其光学特性的变化规律。研究表明，通过改变二元复合缺陷的结构和层数，可以控制禁带中缺陷模式的有无和调节其波长在禁带中的位置，并可使缺陷模恰好位于禁带中心波长处，由此可实现高性能的光学窄带滤波或光子晶体的禁带展宽。该研究结果可为二元复合缺陷光子晶体微腔的设计及其在滤波器、激光器等光学器件中的应用提供参考。

Abstract

The optical characteristics of one-dimensional photonic crystals with two element compound defect layers is studied by transfer matrix method．The process and optical characteristics, which changed from one-dimensional photonic crystals with two element compound defect layers to one-dimensional compound photonic crystals, are mainly discussed. The results indicate that the defect mode and its wavelength can be controlled by the number of layers and structures of the two element compound defects. Thereby it can be realized that optical narrowband filter with high quality or bandgap extension. The results can provide reference for the design of one-dimensional photonic crystals micro cavity with two element compound defect layers, which can be used for making filter, laser, etc.
