摘要

We theoretically investigate the strong coupling in silver-molecular J-aggregates-silver structure sandwiched between two dielectric media by using classical methods.Fresnel equations are employed to solve our proposed structure.The results show that both the reflection and transmission spectra show a Rabi splitting-like line shape,revealing the strong coupling phenomenon.Furthermore,the radiative angle versus incident wavelength exhibits a Fano line shape.The strong coupling phenomenon can be well tuned by controlling the surface plasmon excitation,such as the incident angle and the thickness of the silver films.Our structure has potential applications in quantum networks,optical switches,and so on.
