Abstract: 

Strong coupling is a distinct light-matter interaction regime, in which  the interaction is manifested in coherent oscillations of energy between  matter and a photonic subsystem. The consequence of such a strong  coupling is the adjustment of the energy states of molecules and  materials, which can bring about fascinating chemical and physical  properties, and therefore result in advanced applications in many fields  such as Bose-Einstein condensation and coherent emission, polariton  lasing, superfluidity, quantum information processing, Raman scattering,  chemical landscape, etc. Recently, strong coupling has also  demonstrated profound impacts on the nonlinear optical (NLO) properties  of molecular materials. In this review, the recent research progress in  the field of strongly coupled systems for NLO applications is  summarized. The underlying concepts and the detailed features of  strongly coupled molecular systems are introduced, and the NLO  characteristics of strongly coupled systems are reviewed. Finally, an  outlook of future directions for this emerging field is given.
