Abstract

Spectral properties of the three-layered wedge-cell system of two identical cholesteric layers with an isotropic defect (dye-doped polymer layer) between them were investigated experimentally and theoretically. It was shown that multiple defect modes can be observed in this kind of system’s photonic band gap which widen the application range of system mentioned above such as low threshold lasing, multi-position trigger, multiwavelength filters, light shutters, etc. The supporting simulation was also provided showing an agreement between experimental results and theoretical calculations. The problem was solved by Ambartsumian’s layer addition modified method.

染料掺杂聚合物层的多层胆楔形池系统的光谱奇特性

摘要

通过实验和理论研究了两个相同的胆甾醇层（染料掺杂的聚合物层）之间的两个相同的胆甾醇层的三层楔形电池系统的光谱特性。结果表明，在这种系统的光子带隙中可以观察到多种缺陷模式，从而拓宽了上述系统的应用范围，如低阈值激光，多位置触发，多波长滤光片，光闸等。还提供了实验结果与理论计算之间的一致性。该问题通过Ambartsumian的图层加法修改方法解决。
