GROUP VELOCITY OF PROPAGATION OF ELECTROMAGNETIC EXCITATIONS IN AN IMPERFECT 1D LATTICE OF MICROPORES
Propagation of polariton excitations in a chain of pores is considered. The pores are treated as tunnel connected microresonators containing atomic nanoclusters (quantum points). Within the frameworks of the virtual crystal approximation, specific features of the spectrum of electromagnetic excitations are analyzed that are emerged due to both random variations of the composition of the atomic subsystem and uniform elastic deformation of the tested 1D-structure. The dependence of the group velocity of polariton excitations on the structure defect concentration and the deformation parameter of the tested imperfect system is modeled.
