Abstract
An overview is given on the results of a finite difference time domain evaluation of Maxwell's equations for the near-field response of weakly quantum confined excitons is presented. The analysis is applied to a series of relevant problems in the wide field of SNOM: (i) the modification of the optical response due to the strong spatial gradient and the vectorial character of the field, (ii) the spatial detection of locally varying transition energies, (iii) the excitation of evanescent optical modes that results in the formulation, propagation and scattering of excitonic wavepackets. In the presented scheme experimentally observable signals such as farfield transmission and reflection are calculated.
