Strong Coupling in the Structure of Single Metallic Nanoparticle Partially Buried in Molecular J-Aggregates

Abstract

We investigate the strong coupling phenomenon in the structure of metallic nanoparticle partially buried in molecular J-aggregates. The wave vector and the polarization of incident light impact on the strong coupling phenomenon. With the wave vector and the polarization of incident light in the plane of the interface between the air and molecular J-aggregates, the detuning energies δ reach to the largest. Incident light being injected normally from the air to molecular J-aggregates or from molecular J-aggregates to the air does not influence on δ, but influences on the intensities of the scattering spectra. Our structure has a great help in fabricating the structure which is used to generate the strong coupling phenomenon and also has potential applications in quantum networks, single-atom lasers, quantum information processing, and so on.
