We investigate the strong coupling phenomenon in Kretschmann configuration involving molecular J-aggregates by using surface plasmon polaritons (SPPs) as a light source. SPPs are injected in molecular J-aggregates and propagate along the interface between molecular J-aggregates and the metal film. Both the classical method and Finite difference time domain method are used to show the radiative characteristics of light converted from SPPs in our proposed structure, with the results from the two methods being consistent with each other. Our results show that the radiative angle versus the wavelength shows a Fano line shape and the conversion efficiency of SPPs into light exhibits the strong coupling phenomenon in form of Rabi splitting. Our structure is quite sensitive to the wavelength, which has potential applications in sensing, lasing, optical switching, and nonlinear slow-light devices.
