Abstract:

Transient response in the near-field scattering of a laser pulse on a micron-sized spherical dielectric particle is considered. The spatial area constituting the photonic jet is theoretically investigated and the analysis of the temporal dynamics of jet dimensions as well as of its peak intensity is presented. The jet evolution scenario is shown to include generally the non-resonant and resonant temporal phases; during each phase the photonic jet can change its spatial form and intensity.

Keywords:
