Summary The optical nonlinearities produced by screening of the piezoelectric field byphotogenerated carriers in a -grown (In, Ga)As/(Al, Ga)As single strained-layer quantum well structure are calculated and compared with those in a -grown structure. Nonlinear absorption and refractive index spectra show that screening of the strain-induced electric field by photo-carriers that have escaped from the -grown quantum well produces optical nonlinearities comparable to those in the more conventional -grown quantum well.
