Intensity dependence of signals obtained in four-wave-mixing geometry: influence of higher-order contributions

The nonlinear optical response of a single ZnSe quantum well is investigated in four-wave-mixing geometry. Contributions above third order in the driving fields are quantified by intensity-dependent measurements. Comparison with a microscopic density-matrix approach yield good agreement between expe...

Description
Summary:The nonlinear optical response of a single ZnSe quantum well is investigated in four-wave-mixing geometry. Contributions above third order in the driving fields are quantified by intensity-dependent measurements. Comparison with a microscopic density-matrix approach yield good agreement between experiment and theory. It is found that substantial contributions above third order are generated even at lowest excitation levels necessary in current experiments.
