A nonstationary process of polariton-mode excitation in a two-dimensional (2D) excitonic layer by a light-wave extinction front is analyzed here using the dyadic Green’s function formalism. The electromagnetic response of the 2D excitonic layer includes inhomogeneous radiative exciton-polariton modes corresponding to the complex poles of the matrix Green’s function. On the basis of this theoretical analysis of the nonstationary polaritonic response, an old controversy concerning two different approaches for the description of radiative modes in a 2D excitonic system is resolved.
