dc.description.abstract | Este trabajo corresponde a un estudio teórico de las propiedades ópticas y de impurezas para un electrón confinado en un anillo cuántico de GaAs-(Ga,Al)As sometido a los efectos combinados de campo eléctrico estacionario y radiación láser de alta intensidad no resonante. Los cálculos se hacen en la aproximación de masa efectiva con un proceso de diagonalización para resolver la ecuación de autovalores del Hamiltoniano. Se estudian la absorción óptica y los cambios en el índice de refracción. Los resultados obtenidos sugieren un corrimiento al rojo de las propiedades ópticas en función del campo eléctrico mientras que en el láser no resonante puede inducir efectos combinados de corrimientos al rojo y al azul. El trabajo es útil para entender las propiedades de impurezas en anillos cuánticos sometidos a perturbaciones que rompen la simetría azimutal del sistema tales como campos eléctricos estacionarios y radiación láser no resonante de alta intensidad. | spa |
dc.description.abstract | 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. | eng |
