a 3D schematic of multilayered WS2-based BIC polariton structure emitting vortex beam. b Calculated photon and polariton band structure of multilayered WS2, illustrating the relaxation process, including both direct and indirect excitons. c Corresponding PL spectrum for WS2 multilayers, showing emissions related to both direct and indirect exciton.
