As a new localized state of light, the chiral optical Tamm state exists at the interface between
a polarization-retaining anisotropic mirror and a substance with optical activity. Considering a hybrid
structure comprising a metal-free polarization-preserving mirror and a cholesteric liquid crystal, we
highlight the high Q factor arising from the all-dielectric framework. The intensity of localized light
decreases exponentially with increasing distance from the interface. The penetration of the field into
the cholesteric liquid crystal is essentially prohibited for wavelengths lying in the photonic bandgap
and close to the cholesteric pitch length. The dielectric mirror has its own photonic bandgap. The
energy transfer along the interface can be effectively switched off by setting the tangential wave
vector to zero. The spectral behavior of the chiral optical Tamm state is observed both as reflection and
transmission resonance. This Fano resonance is analogous to the Kopp–Genack effect. Our analytics
are well in line with precise calculations, which may pave a new route for the future development of
intelligent design for laser and sensing applications.
