Abstract:In this paper, the energy levels and nonlinear optical properties modulated by the applied electric field are analytically investigated where a hydrogenic impurity is confined in the GaAs/GaAlAs hexagonal quantum dot(QD). The linear and nonlinear optical absorption coefficients(OACs) have been obtained by using the compact density matrix and iterative approach. In the one electron approximation, an off-center hydrogenic donor impurity is considered, and the results show that the energy levels and nonlinear opt… Show more
