Coupling behavior of WSe2 exciton and photon in an optical microcavity

doi:10.3969/j.issn.1000-5641.202022003

Abstract

Abstract:

In this paper, we study the strong and weak coupling between excitons of a WSe₂ monomolecular thin film and a light field in a self-made Fabry–Pérot semiconductor microcavity at 300 K. The optical properties of the sample were studied using a micro-fluorescence / white light reflection spectroscopy system with integrated angular resolution; the formation of exciton polaritons was observed in the strong coupling region, corresponding to a Rabi splitting energy of 46.7 meV. The theoretical fitting results agree with the experimental phenomena. This lays the foundation for further research on the coherent properties of exciton polaritons, and the study also provide ideas for the application of industrial optoelectronic devices in the future..

Key words: semiconductor microcavity, monomolecular thin film, strong coupling, polariton
