Room temperature Tamm-Plasmon Exciton-Polaritons with a WSe2 monolayer

Abstract

Solid state cavity quantum electrodynamics is a rapidly advancing field which explores the frontiers of light-matter coupling. Plasmonic approaches are of particular interest in this field, since they carry the potential to squeeze optical modes to spaces significantly below the diffraction limit1,2, enhancing light-matter coupling. They further serve as an architecture to design ultra-fast, non-linear integrated circuits with smallest footprints3. Transition metal dichalcogenides are ideally suited as the active material in such circuits as they interact strongly with light at the ultimate monolayer limit4. Here, we implement a Tamm-plasmon-polariton structure, and study the coupling to a monolayer of WSe2, hosting highly stable excitons5. Exciton-Polariton formation at room temperature is manifested in the characteristic energy-momentum dispersion relation studied in photoluminescence, featuring an anti-crossing between the exciton and photon modes with a Rabi-splitting of 23.5 meV. Creating polaritonic quasi-particles in plasmonic architectures with atomic monolayers under ambient conditions is a crucial step towards compact, highly non-linear integrated photonic and polaritonic circuits6,7.
