In Figs. 25d-f and Figs. 25g-i the Rabi-splittings are nearly the same while the detunings at zero angle ∆E are varied. Figs. 25d-f (and Figs. 25g-i) correspond to ∆E = -15.7 meV, ∆E = -29.6 meV and ∆E = -34.6 meV, respectively. Overall, it can be observed that the congregation of the PL spectra directly depends on ∆E. At low ∆E the congregation of PL on the lower polariton is observed at low angles since the resonant condition is met at those angles, at which significant nonadiabatic transitions take place (Fig. and). Similarly, at higher ∆E the resonant condition is met at a higher angle, and as a result, the congregation of PL on the lower polariton is observed at higher angles (Fig. and). The theoretical simulations capture this qualitative trend Fig. -i thus verifying our theoretical understanding.
