Comparative analysis of spatial shapes of photonic jets from spherical dielectric microparticles

A photonic jet is a specific spatially-localized region in the near field of optical radiation scattering by a micron-size particle. The spatial shape and basic characteristics of photonic jets depend to a large extent on the internal structure and size of microparticles. A qualitative classification of morphological types of photonic jets from spherical dielectric microparticles formed in vicinity of the shadow surface is presented. The classification is based on the analysis of their spatial shapes by taking into consideration the dimensional and power characteristics of the jets. Particles with homogeneous and radially inhomogeneous changes in the refractive index are studied.
