A model study of the near-field optical excitation and spatiotemporal dynamics of excitons in semiconductor quantum wells is presented. It is shown that the spatially and temporally localized excitation results in the interference of radiative and nonradiative excitonic contributions, which form a propagating wave packet. The influence of excitation conditions, boundaries, and surface roughness on the wave packet are discussed. The experimentally measurable optical far-field emission of the wave packet is calculated.
