MoSe2 and WSe2 embedded in bragg-cavities with high Q-factors enabling strong exciton-polariton coupling in 2D-systems

Transition metal dichalcogenides (TMDCs) are semiconducting 2D-materials with a direct bandgap in a range of 1.0 to 2.5 eV. The electronic and optical properties of TMDCs are dominated by strongly bound excitons, suitable for the observation of coupled light-matter interactions in highly resonant cavities. From an application point of view, such cavities must not only provide high Q-factors but must also be robust and reproducible.
