The influence of the depolarization effect on the spectral characteristics of intraband absorption on bound-free transitions in semiconductor quantum wells is analyzed using the local and nonlocal theories. The results obtained show that the local theory only qualitatively describes the modification of the bound-free absorption spectrum by the depolarization effect.
