Excitation of surface plexciton wave at interface of a metal and a columnar thin film infiltrated with J-aggregate dyes

Abstract In this paper, we report a theoretical investigation on the excitation of surface plexciton wave at interface of a metal and a columnar thin film infiltrated with J-aggregate dyes using the transfer matrix method in Kretschmann configuration. There exist the regimes of the plasmon–exciton interaction including the weak to strong coupling by tuning structural parameters. We find Rabi splitting energies between 204–378 meV corresponding to the time period 11–20 fs which includes to the fast energy transfer from surface plasmon polaritons to excitons. The phase speed and propagation length of surface plexcitonic waves were in the range of 0.4 to 0.9c and 0.4 to 6 μ m . The results of the time-averaged Poynting vector of surface plexciton waves refer to the localization of them at interface of plasmonic and excitonic mediums.
