Abstract:   (365 Views)
In this study, the interaction of surface plasmon polariton and surface exciton at the interface of a plasmonic medium and a dielectric medium with a C-shaped column morphology consisting of exciton molecules theoretically and classically was investigated in the Kretschmann configuration using the transfer matrix method. The optical absorption spectra of surface plasmon polariton, surface exciton, and surface plexciton have been depicted. The results showed that when the surface plasmon polariton frequency is equal to or close to the frequency of the surface exciton, the polariton mode has two branches, high and low. The mode splitting is caused by the interaction of the surface plasmon polariton and the surface exciton. The characteristics of the splitting energy were analyzed at different structural parameters. The being surface of the plasmon, exciton, and plexciton waves and their localization at the interface between plasmonic and dielectric media were proved by the time averaged Poynting vector and the local absorption.
