| 摘 要： | 利用材料的色散关系和特征矩阵法研究了一维圆柱形光子晶体波导中TE波和TM波模式禁带的变化特征,得出了TE波和TM波模式禁带随色散强度、色散厚度的变化规律.色散强度和色散厚度都会对一维圆柱形光子晶体波导中TE波和TM波的模式禁带产生影响.利用TE波和TM模式禁带随色散强度、色散厚度的变化规律,可实现对一维圆柱形光子晶体波导中TE波和TM波各传输模式的有效控制.

| Abstract: | Using the dispersion relation and the characteristic matrix method the mode band gap of TE wave and TM wave in 1D cylindrical photonic crystal waveguide are studied. Response curves of the mode band gap of TE wave and TM wave versus dispersion strength and dispersion thickness are obtained. Dispersion strength and dispersion thickness can produce apparent effect on the mode band gap. Using these laws can effectively control the mode band gap of TE wave and TM wave in 1D cylindrical photonic crystal waveguide. |
