Abstract

Chiral-selective Tamm plasmon polariton (TPP) has been investigated at the interface between a cholesteric liquid crystal and a metasurface. Different from conventional TPP that occurs with distributed Bragg reflectors and metals, the chiral-achiral TPP is successfully demonstrated. The design of the metasurface as a reflective half-wave plate provides phase and polarization matching. Accordingly, a strong localized electric field and sharp resonance are observed and proven to be widely tunable.

摘要

在手性液晶与超表面的界面处研究了手性选择性塔姆表面等离激元极化激元（TPP）。与由分布式布拉格反射器和金属产生的传统TPP不同，成功证明了手性-非手性TPP。将超表面设计为反射型半波片可提供相位和偏振匹配。因此，观察到了强局域电场和尖锐共振，并证明其具有广泛的可调性。
