Abstract
The effect of the depolarization field on the second-harmonic generation due to resonant intersubband transitions in asymmetric quantum wells is discussed. Calculations are performed in the framework of the perturbative density-matrix formulation with relaxation-time approximation. The results obtained show that in the near-double-resonant system the depolarization effect not only shifts the peak, in the second-harmonic-generation spectrum, but also changes its shape and enhances the maximum value.
