Quantum Emitter Interacting with a WS2 Layer in the Strong Coupling Regime

Abstract

We investigate the spontaneous emission (SE) properties of a quantum emitter (QE) near a WS 2 layer. The QE is placed above the WS 2 layer in a host medium with constant dielectric permittivity and below the WS 2 layer is either the same host medium or Au. The surface plasmon mode at the dielectric/Au interface interacts with the excitons of the WS 2 increasing the Rabi splitting in the SE spectrum of the QE, compared with the dielectric substrate.
