Abstract

The Rashba spin-orbit coupling in nanostructures is an important parameter that can affect their physical properties. Hence, it is demonstrated that the Nonlinear optical properties of quantum dot such as second harmonic generation and optical rectification can be controlled by the Rashba spin-orbit coupling. Also, the effect of electric field and confinement potential strength on the Nonlinear optical properties is examined. Our numerical study shows that magnitude of the second harmonic generation raises when the Rashba strength increases, while its peak position is not shifted. Moreover, the optical rectification of doped Asymmetric quantum dot shifts to higher energies when the electric field enhances.
