Abstract

This work models the Kerr effect in double quantum dot (DQD) ladder-plus-Y system using the density matrix theory. The QD inhomogeneity and wetting layer effect are considered. The Kerr effect is shown to be increased at small pumping where the linear absorption is inhibited. Under very weak probe field in comparison to the pump field, no electromagnetically induced transparency window is shown.
