Abstract

The microcavity in the form of a liquid crystal defect layer embedded in a one-dimensional photonic crystal is considered. The microcavity mode has a tunable radiation decay rate in the vicinity of a bound state in the continuum. It is demonstrated that coupling between the microcavity mode and a Tamm plasmon polariton results in hybrid Tamm-microcavity modes with a tunable factor. The measured spectral features of hybrid modes are explained in the framework of the temporal coupled mode theory.

摘要

研究了嵌入一维光子晶体中的液晶缺陷层形式的微腔。在连续统中的束缚态附近，微腔模式具有可调谐的辐射衰减率。结果表明，微腔模式与塔姆表面等离激元极化激元之间的耦合导致了具有可调谐因子的混合塔姆-微腔模式。在时间耦合模理论的框架内解释了混合模式的测量光谱特征。
