Plexciton modes guided by an exciton slab in a columnar thin film

In this study, we reported the plasmon-exciton coupling for excitation of surface plexciton wave in columnar thin film with a central exciton slab using transfer matrix method Turbadar–Kretschmann–Raether configuration. The optical absorptance spectra plasmon polariton, and was investigated at different structural parameters proposed structure. characteristics modes were analyzed there an anticrossing behavior between polariton branches spectra. Localization on interfaces hybridization plasmons excitons both proved by time-averaged Poynting vector. We found that types regimes from weak to strong could be achieved. obtained high Rabi splitting energy 840 meV corresponding time period 5 fs which indicates fast polaritons excitons.
