The virtual crystal approximation is used for numerical simulation of a polariton spectrum transformation in 1D photonic crystal, consisting of alternating silicon and liquid crystal layers and randomly included admixture layers. The character of dependence of the band gap width and the refractive index upon the concentration of admixture layers is discussed. It is shown that the energy structure of the imperfect superlattice can be significantly altered by implantation of appropriate defect layers. |
