Abstract

The possibility of ultrahigh localization of the optical field near micrometer-sized spherical dielectric particles (zone of “photonic jet”) excited by the pulsed laser radiation is studied theoretically. It is shown for the first time that the photonic jet formed at the nonstationary de-excitation of high-Q resonance modes of a particle can have the sub-diffraction crossdimensional size.
