Nonlinear Optical Properties of Nano- scale V- shaped Quantum Wells

In this paper, we present the results of the investigations on both linear and nonlinear optical refractiveindex changes for GaAs/AlxGa1-xAs V-shaped quantum well in two regimes of narrow and wide well width, with and without the external magnetic field with various intensities of incident photon energy. The results show that the nonlinear response of thestructure can be strengthen by entering the regimes of wide wells and can be weakened by applying a strong magnetic field. The enhancing role of the intensity of the incident photon in nonlinear part of the refractive index change is lead to a reducing effect on the total refractive index change.
