Metal–Dielectric Polarization-Preserving Anisotropic Mirror for Chiral Optical Tamm State

Abstract

This numerical study demonstrates the possibility of exciting a chiral optical Tamm state localized at the interface between a cholesteric liquid crystal and a polarization-preserving anisotropic mirror conjugated to a metasurface. The difference of the proposed structure from a fully dielectric one is that the metasurface makes it possible to decrease the number of layers of a polarization-preserving anisotropic mirror by a factor of more than two at the retained Q-factor of the localized state. It is shown that the proposed structure can be used in a vertically emitting laser.

Tamm plasmon polariton in planar structures: A brief overview and applications

“…Keene and Durach have proposed hyperbolic Tamm plasmons that exist at the interface between a uniaxial metamaterial and a metal [50]. Rudakova et al [51] have numerically studied the existence chiral OTS at the interface of a chiral material like cholesteric liquid crystal (CLC) and multilayer anisotropic mirror followed by a metasurface. They have established that the use of the metasurface can reduce the required number of layers in the multilayer anisotropic mirror at a certain Q-value.…”
