The nonlinear optical properties of MQW structures with binary (ZnSe/ZnMnSe) and ternary (ZnCdSe/ZnSe) wells grown by MBE are compared. Pump‐probe experiments and high‐excitation PL measurements are carried out to study the excitonic nonlinearity as well as gain processes. It is found that the nonlinear optical response is qualitatively different in these two structures as a result of the different kinds of disorder present in the QWs.
