• We study the second order nonlinear optical properties of GaAs quantum dot embedded in Ga 1-y Al y As matrix. The effective mass approximation with the finite confinement potential is used to obtain intraband energy levels and the wavefunctions. Within the framework of density matrix formulation, including the dipole and quadrupole effects the second harmonic generation, the sum frequency generation and the difference frequency generation nonlinear optical processes are investigated in THz region for different dot radii of GaAs quantum dot.
