Bubbles and line splittings

Thanks to our investigations of the two coupled 2LSs, we could obtain a qualitative understanding of the exotic bubbling and splitting of the lines when pump is included in the JCM (Figs. 5.15 and 5.16). However, there are still some disturbing features, like a quadruplet in the emission of the second manifold when the first manifold is in WC, that lack a precise interpretation. It would be very interesting to draw a possible scenario in terms of polaritons (strongly affected by decoherence) that would have as a result such structures, as we did in Fig. 4.1(c) for the two 2LSs. This requires a careful analysis of the distortion of the JC ladder (Fig. 5.12).
