Descripción: The optical properties of exciton polaritons in one-dimensional photonic crystals are theoretically investigated. The periodic photonic structure is formed by two alternating layers, namely a local dielectric layer and a thin semiconductor one which is characterized by a nonlocal excitonic dielectric function. We calculate reflectivity spectra for one-dimensional MgO-CuCl photonic crystals, which exhibit a rich resonance structure because of the optical manifestation of size-quantized excitons. We study the changes in the resonance structure as the thickness of the thin semiconductor layer is varied. It is found that odd quantized-exciton modes are well manifest in the optical spectra in comparison with even states. We have also investigated the effect of both homogeneous bulk damping and interface-induced broadening upon the reflectivity resonances. The broadening due to interface disorder is calculated with the self-consistent Green's function method.
