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

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.
