Features of the fine structure of asymmetric TE and TM modes

Abstract

Abstract This work is devoted to a new section of singular optics supplying a fractional topological charge on the axis. The peculiarity of this type of beams is structural instability. With a small external perturbation, these beams form optical arrays. Such optical vortices can be connected and, as it were, form an integral picture, or decay during propagation due to the fact that each of the vortices receives an additional phase swell. These studies were based on an experimental study and theoretical calculation of beams with a vector structure. And transporting optical vortices with a topological fractional charge, which is evidence of the formation of asymmetric TM (transverse magnetic) and TE (transverse electric) modes in free space. Some features of their vector “thin” structures have been studied in free space.
