Formation of light balls on the basis of interference of oncoming fine-focused beams with different polarizations

Abstract

The paper deals with the formation of spherical intensity distributions on the basis of the interference of oncoming fine-focused vortex beams with different polarization. The formation of three-dimensional distributions is accomplished in a simple way by optimizing the width and position of a single annular diaphragm. The optimum parameters are analytically estimated for a narrow ring aperture, while those for a broad diaphragm are further numerically corrected. It is shown that, depending on the polarization, the order of the vortex singularity and an additional phase advance in one of the beams both solid and hollow light balls of a subwavelength radius consisting of different components of the electric field can be formed.
