We have investigated the nonlinear optical properties of a new class of strained-layer superlattices, the intrinsic Stark effect superlattices (ISES). The superlattices consisted of GaInAs/GaAs grown along the (211)B direction. We observed a shift of the excitonic absorption to higher energies (blue shift) with increasing intensity of the transmitted beam. The observed optical nonlinearity was one order of magnitude stronger than the one due to excitonic screening in the (100) oriented reference material. This effect is attributed to the screening of the internal electric fields by photogenerated carriers. 13 refs., 4 figs.
