一维光子晶体材料中的光学传输特性

Properties of Light Propagation in 1-D Periodic Dielectric Structure

研究了光在一维周期性介电材料中的传播特性 ,指出传统的高反膜只是光子晶体的一个特例 ,从而从光子晶体的角度对多层膜系的设计提出了一条新的思路 ,同时研究了材料的介电常数以及结构与高反带带宽之间的关系。最后通过在多层膜中引入掺杂 (中间一层被另一种介质所代替 ) ,得到第一能隙中掺杂模式的频率与掺杂材料的介电常数之间的对应关系 ,由此提出一种精确测量介质介电常数的方法。

The properties of light propagation in 1 D periodic dielectric structure was discussed. The conventional high reflecting film system is proved to be a special case of 1 D photonic crystal, correspondingly, a structural analysis from the concept of photonic crystal is applied in the design of high reflecting film system. And a new method to accurately measure dielectric index by detecting the defect frequency in 1 D doped photonic crystal is suggested.
