激子在量子发射体和腔体（或表面等离子体激元）的宏观系综中的强耦合可以导致光学性质的急剧变化和色散曲线的修改，其特征在于1 eV量级的正常模式分裂。这种混合能态的巨大变化使许多无与伦比的物理现象和功能成为可能，从提高电导率到控制化学反应。虽然单个发射体与腔体的耦合是一种纯粹的量子力学现象，但涉及大分子系综的强耦合的起源是有争议的。本文研究了罗丹明6 G染料分子与银法布里-珀罗腔的强耦合，发现杂化分子的激发带和发射带之间的斯托克斯位移显著增加。所提出的基础物理学的经验模型要求量子力学宇称选择规则。
Strong coupling of excitons in macroscopic ensembles of quantum emitters and cavities (or surface plasmons) can lead to dramatic change of the optical properties and modification of the dispersion curves, characterized by the normal mode splitting of the order of 1 eV. Such gigantic alteration of the hybrid energy states enables scores of unparalleled physical phenomena and functionalities, ranging from enhancement of electrical conductivity to control of chemical reactions. While coupling of single emitters to a cavity is a pure quantum mechanical phenomenon, the origin of the strong coupling involving large ensembles of molecules is the subject of controversy. In this work, the strong coupling of rhodamine 6G dye molecules with silver Fabry–Perot cavities is studied and the significant increase of the Stokes shift between the excitation and the emission bands of hybridized molecules is demonstrated. The proposed empirical model of the underlying physics calls for the quantum mechanical parity selection rule.
