Abstract

Transient response in the near-field of light wave scattering by micron spherical dielectric particles under laser pulse irradiation is considered. A region of space constituting a photonic jet is theoretically investigated, and the temporal dynamics of the jet size and peak intensity are analyzed. The jet evolution scenario is shown to include generally the non-resonant and resonant temporal phases; a photonic jet can change its spatial form and intensity during each phase.
