Polariton excitations in a non-ideal array of microcavities with quantum dots

Resumo

The polariton spectrum of a one-dimensional non-ideal array of coupled microcavities containing quantum dots has been studied. The specific features of the dispersion of electromagnetic excitations, which are induced in this system both by a variation in the distance between the adjacent microcavities and by a variation in the composition of the quantum dots, have been investigated using the numerical simulation within the framework of the virtual crystal approximation. The density of states of the quasiparticles under consideration has been determined.
