Abstract

The magnitude and time evolution of the third-order nonlinear polarization on two (In,Ga)As/GaAs multiple quantum wells (MQW) Bragg structures with N = 10 and N = 30 with an In content of 3% and a QW width of 8 nm and on a 8.5-nm (In,Ga)/GaAs SQW located at the antinode of a high quality λ long microcavity are investigated. Because all samples are wedge shaped, the detuning between the confined photon mode and heavy-hole exciton transition continuously varies by simply shifting the excitation spot across the sample. Time-integrated degenerate four-wave mixing in the two-pulse self-diffraction geometry is utilized to measure the dephasing rate as a function of detuning between the exciton and the photon mode.
