The effect of optical nonlinearities on the formation of the near-field images over a semiconductor surface is studied by Green's function methods in the case of a nonequilibrium exciton distribution generated by a strongly focused laser pulse. It is shown that inclusion of the third-order nonlinear susceptibility in the system dramatically changes the near-field images if the excitonic system is in resonance. Our calculations predict the dynamic configurational resonances arising as peaks on a∼ 1 ps timescale in the intensity of the near-field image in the far-field pump–near-field probe experiments. For all other cases it is shown that the role of nonlinearity in the formation of the near-field images is insignificant. These results anticipate a further deep insight into exciton dynamics under incoherent nonequilibrium carrier distributions and provide better understanding of ultra-fast near-field experiments.
