Effect of light polarization and dimensions of Λ-type three level cylindrical quantum dot on electromagnetically induced transparency

In this paper, electromagnetically induced transparency (EIT) is investigated in a GaAs cylindrical quantum dot (QD) with parabolic potential. The Schrödinger equation is solved in effective mass, eigenfunctions and eigenvalues of QD. Using obtained eigenfunctions and eigenvalues, susceptibility of cylindrical QD is found. Dependence of electromagnetically induced transparency on radius and height of cylindrical QD, polarization of probe and control lasers, Rabi and probe frequencies, decay rate and detuning of the control laser are also investigated.
