Recent experiments have demonstrated that polariton formation provides a novel strategy for modifying local molecular processes when large ensemble of molecules is confined within an optical cavity. Herein, numerical based on coupled Maxwell–Schrödinger equations examined simulating in realistic cavity structure under collective strong coupling. In this approach, only few molecules, referred to as quantum impurities, are treated mechanically, while the remaining macroscopic layer and modeled using dielectric functions. When single electronic two-level system embedded Lorentz medium two-dimensional Bragg resonator, our simulations reveal polariton-induced Purcell effect: radiative decay rate impurity significantly enhanced by frequency matches frequency, can sometimes be greatly suppressed near resonance with bulk forming addition, approach demonstrates absorption light exhibits Rabi-splitting-dependent suppression due inclusion structure.
