  A phenomenological theory of luminescence properties of one-dimensional
resonant photonic crystals is developed within the framework of classical
Maxwell equations with fluctuating polarization terms representing non-coherent
sources of emission. The theory is based on an effective general approach to
determining linear response of these structures and takes into account
formation of polariton modes due to coherent radiative coupling between their
constituting elements. The general results are applied to Bragg
multiple-quantum-well structures, and theoretical luminescence spectra of these
systems are compared with experimental results. It is shown that the emission
of such systems can be significantly influenced by deliberately introducing
defect elements in the structure. The relation between absorption and
luminescence spectra is also discussed.
