a Sketch of the MoS2 BL cavity measured in pump-probe, exciting the hIX spectral region and probing the polariton states formed around XA−BL. b Color map of the 1-R spectra of the BL microcavity as a function of the delay time, exciting the hIX and probing the MPB-LPB spectral region. c 1-R spectra of the BL microcavity pumping the hIX, taken at different pump-probe delay times. Already after 1 ps, the polariton peaks are clearly recovered.
