Abstract

Linear and nonlinear optical absorption coefficients (ACs) and refractive index changes (RICs) between the ground and the excited states of the GaAs spherical quantum dot (QD) under the effect of Kratzer confining potential and laser field have been investigated theoretically. The electronic energy levels and their corresponding wave functions are obtained by solving Schrödinger equation using finite difference method within the effective mass approximation. The dependency of energies, probability densities, dipole matrix elements on the Kratzer potential parameters and on the size of QD are investigated. The use of density matrix formalism is made to study the variations in linear, nonlinear ACs and RICs with the energy and intensity of the laser field. Also the effect of variation of the QD size and Kratzer potential parameters on linear, nonlinear ACs and RICs are studied. Graphical abstract
