Peculiarities of Propagation of Electromagnetic Excitations through Nonideal 1d Photonic Crystal

Vladimir V. Rumyantsev

Abstract

Nonideal 1D photonic crystal is modeled as a macroscopically homogeneous layered system (which is onedimensional Si-liquid crystal superlattice with two elements-layers in the cell) with randomly included admixture layers. The virtual crystal approach which is the method to describe quasi-particle excitations in disorder media is used. Peculiarities of the dependence of photonic band gap width on admixture layers concentration have been studied. The results are the evidence of substantial polariton spectrum reconstruction caused by presence of defect layers.
