We have designed and experimentally realized a polaritonic topological insulator based on bulk transition metal dichalcogenide crystals (TMDC, ~40nm-thick WS2 film). We have demonstrated that due to their high refractive index and the presence of exciton modes in the optical range, they represent an excellent platform for topological polaritonics, offering both excellent confinement and strong light-matter interactions in a single material. The successful patterning of TMDC into the topological crystal was demonstrated and emergence of the topological polaritonic boundary modes was directly confirmed by the back focal plane imaging and real space imaging techniques.
