Abstract

We present a novel heterodyne-detected four-wave mixing technique, which determines the third-order nonlinear polarization in phase and amplitude by spectral interferometry. It allows us to measure the resonant transient four-wave mixing of single localized excitons, both frequency and time-resolved. In the signal, the strength of the coupling between two probed exciton transitions is directly observable. Applying a strong optical pump pulse, we observe optical Rabi oscillations of the exciton polarization. Observing decay of the third-order polarization after the pump pulse, we can exclude the presence of signi£cant excitation-induced dephasing.
