The saturation of absorption and negative nonlinear index changes in the In0.530Al0.141Ga0.329As/In0.530 Ga0.470As multiquantum-wells (MQW) were directly measured with picosecond pulses. Associated loss-related nonlinear figures of merit were calculated. The fluences required to effect the nonlinear index changes measured were similar to those inside a semiconductor laser.
