Özet

In this paper, electronic as well as the optical properties of an electron in both symmetric and asymmetric double quantum wells which consist of a harmonic potential with an internal Gaussian barrier, under the nonresonant intense laser field are investigated. The electronic structure has been obtained by using the two-dimensional diagonalization method. To calculate the linear and nonlinear absorption and refractive index coefficients the standard density matrix formalism combined with the perturbation expansion method is used. Obtained results show that the electronic and, therefore optical properties of the Parabolic-Gaussian double quantum wells considered can be adjusted to obtain a suitable reply for the specific aims by alterations of the parameters such as the well and barrier widths, well depth, barrier height and inter-wells coupling, in addition to the applied non-resonant intense laser field.
