Özet

This work presents the results of the theoretical study of the effects of non-resonant intense laser field, electric and magnetic fields on optical responses of GaAs n-type delta-doped quantum well associated to the electron transitions. Optical properties are obtained by using the compact-density matrix method. The numerical results show that the applied external fields have a significant effect on the optical characteristics of these structures, such as the optical absorption coefficient and refractive index. Thus, such futures can be use to tune the optical properties of doped semiconductor heterostructures. (C) 2018 Elsevier GmbH. All rights reserved.
