Analytical expressions of optical rectification in Morse quantum well are obtained by density approach and iterative method. Numerical results are illustrated for a typical GaAs/AlGaAs Morse quantum well. It is found that the optical rectification coefficient increases with the enhancement of the asymmetry of Morse quantum well.
