论文摘要
使用有效的转移矩阵方法（TMM）对具有和没有缺陷的一维光子晶体进行了数值研究。已布置了TMM的详细数值配方。对于周期性光子带隙（PBG）结构，验证了分散关系。当存在缺陷时，可以将传输频谱分解为一个或多个准分子模式。状态（DOS）的密度是从透射光谱的相衍生物获得的。当激发源位于准模式的峰值时，还可以获得GREEN的功能，显示出许多更清晰的模式特征。
1-Dimensional (1D) photonics crystals with and without defects have been numerically studied using efficient Transfer Matrix Method (TMM). Detailed numerical recipe of the TMM has been laid out. Dispersion relation is verified for the periodic Photonics Band Gap (PBG) structure. When there are defects, the transmission spectrum can be decomposed into one or more quasi modes with excellent agreement. The Density of States (DOS) is obtained from the phase derivative of the transmission spectrum. Green's function is also obtained showing much sharper mode characteristics when the excitation source is localized at the peaks of the quasi modes.
