Abstract


In this paper, we investigated the realization of electromagnetically induced transparency (EIT) in a rectangular quantum dot (QD) with a single electron in the presence of probe and control laser fields. The lowest three levels of the confined electron that form ladder and V configuration were chosen. We discussed the dependence of density matrix elements   for ladder configuration and  for V configuration on detunings of the probe field for various values of quantum dot dimensions. This dependence is discussed for both cases, at cryogenic temperatures when spontaneous emission dominates the relaxation mechanism and at room or higher temperatures when dephasing rate cannot be neglected.

Keywords
