Özet

In this paper, we investigate the electronic and optical properties of an electron in both

symmetric and asymmetric double quantum wells that consist of a harmonic potential with an

internal Gaussian barrier under a nonresonant intense laser field. The electronic structure was

obtained by using the two-dimensional diagonalization method. To calculate the linear and nonlinear

absorption, and refractive index coefficients, a combination of the standard density matrix formalism

and the perturbation expansion method was used. The obtained results show that the electronic

and thereby optical properties of the considered parabolic–Gaussian double quantum wells could

be adjusted to obtain a suitable response to specific aims with parameter alterations such as well

and barrier width, well depth, barrier height, and interwell coupling, in addition to the applied

nonresonant intense laser field.
