In this paper, we have performed a theoretical study on nonlinear optical rectification (OR) and second harmonic generation (SHG) for three-level dome-shaped InAs/GaAs quantum dots (QDs) in the presence of wetting layer (WL). We used the compact density matrix framework and effective mass approximation to investigate the second order nonlinear phenomena on InAs/GaAs QD. It is demonstrated that second harmonic generation (SHG), optical rectification (OR), and their mutual absorption and refractive index changes are quite sensitive to the size of QDs. The size variations have profound irregular behavior owing to distribution of envelope function on WL and QD simultaneously. Moreover it is found that R=13 nm is a critical radius where the regular variation takes place. It is shown that size variation causes blue shift until Critical radius (R=13 nm) and after that, increasing the QD size lead to redshift in second order phenomena.

Magneto Optical Effect

The photon-photon scattering predicted by quantum electrodynamics can give rise to second-harmonic generation of intense laser radiation in a dc magnetic field due to broken symmetry of interaction even in the “box” diagram approximation. This effect is possible only when the field system (i.e. optical wave+dc field) is inhomogeneous, in particular when a Gaussian laser beam (i.e. nonplane wave) propagates in either homogeneous or inhomogeneous dc magnetic field.
