| Popis: | Cavity-integrated transition metal dichalcogenide excitons have recently emerged as a promising platform to study strong light-matter interactions and related cavity quantum electrodynamics phenomena. While this exciton-cavity system is typically modeled as coupled harmonic oscillators, to account for the rich solid-state environment the effect of exciton-phonon interaction needs to be incorporated. We model the system by including a phenomenological deformation potential for exciton-phonon interactions and we elucidate the experimentally measured preferential coupling of the excitonic photoluminescence to the cavity modes red-detuned with respect to the exciton resonance. Furthermore, we predict and experimentally confirm the temperature dependence of this preferential coupling. By accurately capturing the exciton-phonon interaction, our model illuminates the potential of cavity-integrated transition metal dichalcogenides for development of low-power classical and quantum technologies.
