In contrast to most of the previous publications that has addressed the dependency of the defect mode on temperature in planner one‐dimensional photonic crystal, we study this dependency in cylindrical photonic crystal taking into consideration both thermal‐optical and thermal expansion effects. Our analysis, based on the cylindrical transfer matrix, is conducted for both types of polarized electric and magnetic waves. Our structure is composed of arrays of cylindrical coaxial shells of TiO₂ and Al₂O₃ with single defect layer. Numerical results show that the defect mode's wavelength can be effectively tuned, following a linear relation, by changing the temperature for both types of polarized waves. In addition, the peak transmittance is dependent on the number of periods and the starting inner radius. Moreover, decreasing the inner radius is associated with separation between the two polarizations.

圆柱光子晶体结构中可调谐缺陷模式的数值分析

与大多数以前的出版物已经讨论了缺陷模式对平面一维光子晶体中温度的依赖关系相反，我们研究了圆柱光子晶体中的这种依赖关系，同时考虑了热光效应和热膨胀效应。我们基于圆柱传输矩阵对两种类型的极化电波和磁波进行分析。我们的结构由TiO ₂和Al ₂ O ₃的圆柱形同轴壳阵列组成具有单个缺陷层。数值结果表明，通过改变两种类型的极化波的温度，可以按照线性关系有效地调整缺陷模式的波长。另外，峰值透射率取决于周期数和起始内半径。此外，减小内半径与两个极化之间的间隔有关。
