The resonant splitting of optical Tamm state numerically is demonstrated. The Tamm state is localized at the interface between a resonant chiral medium and a polarization-preserving anisotropic mirror. The chiral medium is considered as a cholesteric liquid crystal doped with resonant dye molecules. The article shows that the splitting occurs when dye resonance frequency coincides with the frequency of the Tamm state. In this case the reflectance, transmittance, and absorptance spectra show two distinct Tamm modes. For both modes, the field localization is at the interface between the media. The external field control of configurable optical and structural parameters paves the way for use in tunable chiral microlaser.
通过数值模拟证明了光学塔姆态的共振分裂。塔姆态局域于共振手性介质与保偏各向异性镜之间的界面处。手性介质被视为掺杂有共振染料分子的胆甾相液晶。文章表明，当染料共振频率与塔姆态频率一致时会发生分裂。在这种情况下，反射率、透射率和吸收率光谱显示出两种不同的塔姆模式。对于这两种模式，场局域均位于介质之间的界面处。可配置光学和结构参数的外部场控制为可调谐手性微激光器的应用铺平了道路。
