摘    要:研究了含色散介质的一维光子晶体微腔的透射谱,对色散介质采用Lorentz振子模型,腔模的频率设置在光子晶体带隙中心。发现当吸收可以忽略时,色散效应将导致在腔模附近有很高的态密度,与此相应地在透射谱中出现一个较宽的透射带。当吸收存在时透射带中心的透射峰消失,但带尾的透射峰依然存在。

关 键 词:光子晶体  态密度  色散微腔

Abstract:The transmission spectrum of the 1D photonic crystal with dispersive cavity is studied in this paper.The dispersive medium is described by the Lorentz oscillator model,and the frequency of the cavity mode is set at the center of the gap.When the absorption is negligible,the density of states near the cavity mode is very high,and there is a comparatively wider transmitted band appearing in the transmission spectrum.When absorption is included,the transmission at the central frequency disappears,but the transmission still exists near the tail of the transmission band.
Keywords:photonic crystal  Density of States  dispersive cavity
