The resonant nonlinear optical response of the intersubband transitions in GaN/AlGaN quantum wells was measured. The prospects of using such structures as building blocks for all-optical nonlinear switches were also discussed. The measured value for the nonlinear susceptibility is found to be much smaller than previous theoretical predictions.
