Abstract
A theoretical study of the impurity effects on nonlinear optical properties of a spherical quantum dot under applied magnetic field is performed. Based on the effective mass approximation, a strong perturbation theory is proposed to calculate the linear, the third-order nonlinear and the total optical absorption coefficients. The results suggest that the optical properties of the hydrogenic donor confined in a spherical quantum dot depend strongly on the confinement strength (or dot size), the incident optical intensity, the applied magnetic field intensity and the relaxation time. We also compare our results with the existing results.
