摘要:
提出了用正、负折射率介质层交替排列构成的一维光子晶体模型, 并且用传输矩阵法计算了该模型的透射谱, 从理论上 分析了其带隙结构。发现负折射率介质层的引人导致了奇异的带隙特性;禁带很宽, 禁带宽度??2 △ω/ω0。趋于?2? , 导带为没有振荡 的尖锐峰?? 禁带宽度对折射率对比度和周期数的变化非常敏感。
Abstract:
The authors proposed a new model of one-dimensional photonic crystal composed of alternately arranged RHM and LHM layers, calculated numerically the transmission spectra of the model with the transfer matrix method, and theoretically analyzed characteristics of the band-gap structure. The intro? duction of negative refractive index layers (i.e. LHM layers) gave rise to the peculiar band-gap structure as follows. Firstly the forbidden bands were extremely wide and the transmission bands were extremely sharp and without oscillations; secondly the forbidden band width tended to 2△w/w0 =2 and it was very sensitive to change of the ratio of refractive indices and the number of periods.
