“…The nonlinear optical properties of QWs, in particular optical absorption coefficients (OACs), the change of index changes (RICs), second (SHG) and third harmonic generations (THG) or nonlinear optical rectification (NOR), have attracted a lot of attention in theoretical studies in recent years [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. For example, Aytekin et.…”

In the present study, the effect of the depth of the confinement potential on the nonlinear optical of a GaAs quantum well with short-range bottomless exponential potential is studied in detail. The energy eigenvalues and eigenfunctions of this structure are calculated within the framework of effective mass and envelope function approximations. Analytic formulas for the linear, third-order nonlinear and total absorption coefficients and relative refractive index changes are obtained using the compact-density matrix approach (CDMA) and iterative method. Based on this model, our obtained numerical results are reported as a function of incident photon energy for several values of the depth of the confinement potential. The results show that the linear, third order nonlinear, and total absorption coefficients and relative refractive index changes are strongly affected by the depth of the confinement potential.

“…The development of high‐powered adjustable laser sources, such as free‐electron lasers, has motivated research activities on the interaction of ILFs with carriers in semiconductor nanostructures . Recently, the effect of the ILF on the electronic and optical properties of quantum wells (QWs) has been particularly studied in detail by many authors . It has been shown that the electronic and optical properties of the band edge‐engineered QW structures can be significantly adjusted by modulating the ILF amplitude, mainly due to the changes of the confinement potential size and shape induced by the radiation .…”

In this paper, the effects of the intense laser field (ILF) and position dependent mass (PDM) on the electronic structure in a Gaussian quantum well are theoretically deduced by using the diagonalization method for obtaining energy levels and corresponding wave functions. We find that, in the case of narrow PDM distribution, the dependence of the energy levels on the effective length of the electron mass distribution becomes more apparent, and the evolution of the dressed mass with ILF is significant. Given this feature, it is more meaningful to take into consideration the PDM of the electron in the low dimensional semiconductor heterostructures under the ILF.
