In this Chapter, we solve the exciton-cavity photon coupling
analytically with the linear model and analyze its properties of
emission in the presence of decoherence (dissipation and incoherent
pump). The results presented here have been published in the
references 4, 6,
10, 16 and
17 of the list of my publications .3.1 The last one is
a Mathematica plotter of the spectra of emission, that might be
useful to follow the argumentation.
