Abstract
Achieving directional exciton energy transport can revolutionize a plethora of applications that depend on exciton energy transfer. In this study, we theoretically analyse a system that comprises a collection of chiral quantum emitters placed in a plasmonic setup made up of a metal nanoparticle trimer. We investigate the system by pumping left and right circularly polarized photons to excite the system. We observe that the generated localized surface plasmon modes are polarization-depended, causing chiral coupling between the quantum emitters and the plasmon optical modes. Based on the plasmon field intensity profiles, we show that directional exciton transport can be obtained when the light–matter interaction becomes adequately strong, leading the system towards the strong coupling regime.
