The second-order nonlinear optical effect in asymmetric quantum wells is investigated. By using compact density-matrix approach, the analytical expression of the second-order nonlinear optical coefficient is obtained. The results show that the second-order nonlinear optical coefficient increases with the increasing of the asymmetry of quantum well. In addition, the nonlinear optical coefficient which obtained in this asymmetric quantum well is very larger than that obtained in bulk GaAs.
