The strong coupling regime is maintained at lasing threshold since the coherent nonlinear emission from the lower polariton branch (LPB) occurs at zero in-plane wavevector well below the uncoupled cavity mode. The contribution of multiple localized polariton modes above threshold and the non-thermal polariton statistics show that the system is in a far-from-equilibrium regime, likely related to the moderate photon lifetime and in-plane photonic disorder in the cavity. |
