The results of a numerical calculation of the dispersion and photoluminescence spectra of mixed modes are analyzed depending on the decay of mechanical excitons and the angle of emission of radiation into vacuum in the vicinity of the critical values ​​ and . It is shown that the mechanism of line formation depends significantly on the value of the light-exciton interaction parameter: at the value and weak polariton effect causes strong interference of mixed exciton-inhomogeneous waves, and when we have and dominates the role of strong interference of intermediate mixed polaritons against the background of anomalous dispersion. The superposition of M1 and M2 waves with strongly asymmetric and symmetric contours forms an almost symmetric resulting spectral contour with a maximum at the critical frequency
