手性雕塑薄膜中产生光谱空穴的第三种方法

Third method for generation of spectral holes in chiral sculptured thin films

Fei Wang, Akhlesh Lakhtakia

摘要:

在周期性结构手性材料中引入中心层缺陷或中心扭曲缺陷会在垂直入射平面波的汇款光谱中产生圆偏振敏感光谱孔。我们提出并从理论上建立了第三种方法,使用两段手性雕刻薄膜(STFs)产生这样的光谱孔。所提出的器件的两个部分具有相同的周期性和旋向性,但它们的介电特性不同,并且以特定的方式相关。伪各向同性的概念与所提出的装置的生产高度相关。

英文摘要:

The introduction of either a central layer defect or a central twist defect in a periodic structurally chiral material generates circular-polarization-sensitive spectral holes in the remittance spectrums for normally incident plane waves. We propose and theoretically establish here the third method to generate such spectral holes using two-section chiral sculptured thin films (STFs). Both sections of the proposed device have the same periodicity and handedness, but their dielectric properties are different and related in a specific way. The concept of pseudoisotropy is highly relevant for the production of the proposed device.
