Abstract
Photonic jets can be produced by the illumination of a micrometer dielectric particle by an optical plane wave, and are characterized by a narrow elongated focal volume. Bessel beams have been widely studied in recent decades and are commonly referred to as being "diffractionless" over long distances. The Bessel beam aspects of photonic jets are investigated in this manuscript. In particular, we show that photonic jets take their properties from Bessel propagative beams, but more complex phenomena are involved.
