Abstract:

The influence of the depolarization effect on the optical rectification in electric-field-biased GaAs quantum well is studied using relaxation time approximation and a compact density-matrix approach. The results obtained show that the depolarization effect shifts the position of the resonance peak. For three different bias field, , , and , the peak position is , and , respectively. The shift of the peak position is 5.96 , 5.99 and 6.28, respectively, which increases with the bias field.
