In this review we look at the concepts and state-of-the-art concerning the strong coupling of surface plasmon-polariton modes to states associated with quantum emitters such as excitons in J-aggregates, dye molecules and quantum dots. We explore the phenomenon of strong coupling with reference to a number of examples involving electromagnetic fields and matter. We then provide a concise description of the relevant background physics of surface plasmon polaritons. An extensive overview of the historical background and a detailed discussion of more recent relevant experimental advances concerning strong coupling between surface plasmon polaritons and quantum emitters is then presented. Three conceptual frameworks are then discussed and compared in depth: classical, semi-classical and fully quantum mechanical; these theoretical frameworks will have relevance to strong coupling beyond that involving surface plasmon polaritons. We conclude our review with a perspective on the future of this rapidly emerging field, one we are sure will grow to encompass more intriguing physics and will develop in scope to be of relevance to other areas of science.
在这篇综述中，我们探讨了表面等离激元模式与量子发射器（如 J-聚集体中的激子、染料分子和量子点）相关态之间强耦合的概念和最新进展。我们参考了涉及电磁场和物质的一些例子来探索强耦合现象。然后，我们简要描述了表面等离激元的相关背景物理。接下来，我们全面回顾了历史背景，并详细讨论了表面等离激元与量子发射器之间强耦合的最新相关实验进展。然后深入讨论并比较了三个概念框架：经典、半经典和全量子力学；这些理论框架将与表面等离激元之外的强耦合相关。最后，我们对这个快速发展的领域的未来进行了展望，我们相信这个领域将会涵盖更多有趣的物理，并在范围上扩展到与其他科学领域相关。
