The strong coupling between excitons and Fabry-Perot (F-P) cavity modes in tungsten sulfide (WS2) thin layers was studied. By using home-made micro-reflectance spectroscopic technique, we observed the anti-crossing behavior between cavity mode and excitons with flake's thickness dependence. Giant Rabi splitting of similar to 270 meV for A exciton and similar to 780 meV for B exciton were obtained from the fitting of the cavity polariton dispersions by use of the coupled oscillators model.
