| 摘 要： | 用FDTD方法计算了二维正方形复式晶胞光子晶体的光子特性．通过光子能带结构、光子态密度的分布以及沿ГX方向透射谱的计算，发现透射谱光子带隙的位置与能带结构符合得很好．光子态密度的分布也表明存在全带隙的光子频率范围，进一步研究给出这种结构光子晶体全带隙存在的物理起源．

| Abstract: | The photonic properties of a two-dimensional complex photonic crystal (PC) of square lattice were calculated by finite different time domain (FDTD) method. The photonic band structure, photonic density of states, the transmission and reflection coefficients along ГX direction were obtained. The results indicate a clear correspondence between the photonic band structure and the transmission spectra along ГX direction. The photonic band structure was also shown by the photonic density of states. Furthermore, the theoretical explanation for the opening of the band gap was given. |
