摘要: 光子晶体即光子禁带材料,从材料结构上看,光子晶体是一类在光学度上具有周期性介电结构的人工设计和制造的晶体。与半导体晶格对电子波函数的调制相类似,光子带隙材料能够调制具有相应波长的电磁波---当电磁波在光子带隙材料中传播时,由于存在布拉格散射而受到调制,电磁波能量形成能带结构。能带与能带之间出现带隙,即光子带隙。所具能量处在光子带隙内的光子,不能进入该晶体。光子晶体和半导体在基本模型和研究思路上有许多相似之处,原则上人们可以通过设计和制造光子晶体及其器件,达到控制光子运动的目的。光子晶体(又称光子禁带材料)的出现,使人们操纵和控制光子的梦想成为可能。
本文将通过第三章的理论基础,采用R-soft软件进行仿真模拟,模拟光子晶体环形腔滤波器的结构。并通过引入一组点缺陷实现了单纵模滤波特性。在此基础上,我们通过分别改变整体介质柱折射率,改变点缺陷折射率,改变点缺陷半径,同时对滤波光谱图进行了分析。结果表明选择不同的参数可以实现滤波特性的可调性,这将对今后在集成光子晶体器件中设计多通道光滤波器提供重要的理论参考。
