Quantum Dots

We present a microscopic theory for a finite number of uncoupled QD on the basis of microscopic Maxwell-Bloch equations. Our theory describes the degeneracy due to the coupling of states in the different quantization directions, the anisotropy concerning arbitrary shapes of the carrier confined potentials, the number of the states as well as carrier-field interactions. We present the numerical solutions of Maxwell-Bloch equations for a sample of a hundred uncoupled dots made with GaAs embedded in the background material AlAs. By considering a two level model for electrons and holes states, we've evaluated the matrix dipole elements and carrier-light field dynamics.
