Paper Abstract

Currently, optical vortices (OVs) which are areas of circular motion of light flux in an electromagnetic wave, are being actively studied. Optical vortices can be divided into longitudinal OVs, where the axis of circular flow coincides with the direction wave propagation, and transversal OVs, where the axis is perpendicular to the wave propagation direction. Airy rings in a focal plane of a lens may serve as an example of transversal OVs. For both longitudinal and transversal OVs the OV axis is the line where the field amplitude is equal to zero. The phase is assumed to be uncertain, or singular, along the OV axis. We report a detailed study of a structure of a transversal OV created in an interference field of two two-dimensional (2D) Gaussian waves and the topological reactions which can happen in the interference field. A physical reason, which determines the direction of light flow circulation is discussed.
