Influence of the depolarization effect and the nonparabolicity on the second-harmonic generation spectrum in doubly resonant asymmetric quantum well systems

摘要

The second harmonic generation due to the intersubband transitions in the doubly resonant nonparobolic quantum well systems is discussed theoretically, employing the self- consistent field method. It was shown that the correct description of the modification of the second-harmonic generation spectrum resulting from the nonparabolicity of the subbands have to take into account the depolarization effect.
