结构和缺陷对二维光子晶体传输性质的影响

EFFECT OF STRUCTURE AND DEFECT ON TRANSMITTED CHARACTER OF 2D PHOTONIC CRYSTAL

用转移矩阵方法计算了二维光子晶体的传输性质 ,讨论了不同极化光的透射行为 ,比较了正方点阵、有心正方点阵、含缺陷有心正方点阵光子能带对透射特性的影响 ,获得了第一禁带特性与光子晶体结构的一些基本关系 .

The transmitted character of 2D photonic crystal was calculated by transfer matrix method (TMM), and the transmission behavior of the different polarized light was discussed. The result provides the basic relation of the structure and the first band gap of the photonic crystal, comparing effect of square lattice, centered square lattice and centered square lattice with defect on the transmission characteristic.
