Exciton polaritons (EPs) are half-light, half-matter quasiparticles formed due to the coupling between photons and excitons in semiconductors. Their uniqueness lies at the strong light-matter interactions and long-distance transport, thus promising for many novel applications in photonics, information, and quantum technologies. Recently, EPs in group-VI transition-metal dichalcogenides (TMDs) have attracted a lot of research interest due to their room-temperature stability, long-distance propagation, and controllability through electric gating, valley-selective optical pumping, and precise thickness control. In this progress report, recent studies of EPs in TMDs are reviewed, highlighting their key properties and functionalities, and then discussing the potential directions for future research.
