This study reports the observation of strong light-matter coupling and the formation of microcavity polaritons in a two-dimensional (2D) atomic crystal of molybdenum disulphide (MoS₂) embedded in a dielectric microcavity at room temperature. The strong coupling regime is achieved when the interaction between 2D excitons and cavity photons is stronger than the dissipation rates of the light and matter entities. This results in the formation of half-light-half-matter bosonic quasiparticles called microcavity polaritons. The study demonstrates that strong coupling can be achieved in a disorder-free potential landscape, which is essential for the development of practical polaritonic circuits and switches. MoS₂ is a promising 2D material for optoelectronic applications due to its unique electronic and optical properties. It exhibits a direct bandgap in the monolayer form, which allows for efficient light emission and absorption. The study shows that when MoS₂ is embedded in a dielectric microcavity, the coupling between the 2D excitons and the cavity photons leads to a Rabi splitting of 46 meV, indicating strong coupling. The angle-resolved reflectivity measurements reveal the formation of lower and upper polariton branches, with the upper branch showing stronger emission at large angles. The photoluminescence (PL) measurements also confirm the presence of these polariton branches, with the emission intensity showing an antenna-like pattern due to the interaction between the in-plane component of the cavity photons and the MoS₂ excitons. The study highlights the potential of 2D materials for realizing practical polaritonic devices, such as spin switches, due to their high exciton binding energy and direct bandgap. The results demonstrate that strong coupling can be achieved in 2D materials at room temperature, which is a significant step towards the development of practical polaritonic devices. The findings also show that the highly anisotropic nature of the exciton orientation in MoS₂ leads to distinct emission patterns compared to other MC polariton demonstrations in quantum wells, wires, and dots. The study provides a foundation for further research into the application of 2D materials in optoelectronic devices and polaritonic circuits.This study reports the observation of strong light-matter coupling and the formation of microcavity polaritons in a two-dimensional (2D) atomic crystal of molybdenum disulphide (MoS₂) embedded in a dielectric microcavity at room temperature.
