We discuss chiral structures in self-organizing, artificial, and biological materials. A review of experimental studies and recent advances in the localization of light in chiral structures is given. The behavior of polarized resonant modes in such structures is examined using the example of a one-dimensional photonic crystal containing liquid crystal materials. The anomalous spectral shifts of transmission peaks are interpreted as the contribution of the geometric phase caused by the twisting of the layers of the liquid crystal. The optical Tamm state localized at the boundary between chiral and nonchiral mirrors in the form of a cholesteric layer and a polarization-preserving anisotropic mirror is analytically and numerically described. Considerable attention is paid to the presentation of the properties of localized optical modes in the cholesteric with a resonant metal-dielectric nanocomposite. New possibilities for controlling the properties of the photonic structure are not...

手性光子结构中的局域模

我们讨论自组织，人工和生物材料中的手性结构。综述了实验研究和光在手性结构中的定位的最新进展。以包含液晶材料的一维光子晶体为例，研究了这种结构中的偏振共振模式的行为。透射峰的异常光谱偏移被解释为由液晶层的扭曲引起的几何相位的贡献。分析和数值描述了以胆甾型层和保偏各向异性镜的形式定位在手性和非手性镜之间的边界处的光学Tamm状态。在具有共振金属-介电纳米复合材料的胆甾型中，局部光学模式的性质的表现引起了人们的极大关注。控制光子结构特性的新可能性并不是...
