This work corresponds to a theoretical study of the optical properties of impurities for an electron confined in a GaAs- (Ga, Al) As quantum ring under the combined effects of stationary electric field and high intensity non-resonant laser radiation. Calculations are made on the effective mass approximation with a diagonalization process to solve the eigenvalues equation of the Hamiltonian. The optical absorption and the changes in refractive index are studied. The results suggest a redshift of the optical properties as a function of the electric field while the non-resonant laser can induce combined effects of redshifts and blueshifts. The work is useful for understanding the properties of impurities in quantum rings subjected to perturbations which break the azimuthal symmetry of the system such as non-stationary resonant electric fields and high-intensity laser radiation. © 2015.  © 2015.
