In this work, the simultaneous effects of aluminum concentration, hydrostatic pressure and temperature on the nonlinear optical rectification (OR), second- and third-harmonic generation (SHG and THG) in a GaAs/Ga[Formula: see text]Al[Formula: see text]As morse quantum well (QW) are studied. The expressions of OR, SHG and THG in morse QW were derived with the use of the compact-density-matrix approach and iterative method. The simultaneous effects of aluminum concentration, hydrostatic pressure and temperature on the effective mass have been taken into account. It is found that (1) the presence of the aluminum concentration, hydrostatic pressure and temperature have a great influence on the symmetry of the system, the nonlinear OR, SHG and THG. (2) the variation of the resonant peaks of the OR and SHG shows complicated behavior as the temperature changes. (3) the temperature effect is weaker than the aluminum concentration and hydrostatic pressure effects on the nonlinear OR, SHG and THG. The influences of different parameters of GaAs/Ga[Formula: see text]Al[Formula: see text]As morse QW and applied field strengths on the nonlinear OR, SHG and THG are discussed.

Abstract In this paper, the effects of external electric, magnetic and non-resonant intense laser fields on the nonlinear optical rectification (NOR), second-harmonic (SH), and third-harmonic (TH) generation in a GaAs quantum well with asymmetrical Gaussian potential are theoretically investigated. Firstly, the energy eigenvalues and eigenfunctions of a single electron confined in the structure are obtained by using the diagonalization method within the framework of the effective-mass and parabolic band approaches. Then, using these energy eigenvalues and eigenfunctions, expressions derived within the compact density matrix approximation has been employed to calculate the coefficients of the nonlinear optical response in the structure. The obtained simulation results show that the influence of the external fields leads to significant changes in the coefficients of nonlinear optical rectification, second and third harmonic generation in the system. As a result, it has been seen that the amplitude and position of the peaks of nonlinear optical rectification, second and third harmonic coefficients can be controlled by changing the applied external fields.
