Mode matching in the field speckle pattern after graded-index fibers
A. Volyar, M. Bretsko, Ya. Akimova +1
We have developed and implemented a new technique of parallel information transmission through a multimode graded-index fiber in real time based on the approach of intensity moment…
Fine structure of perturbed Laguerre-Gaussian beams: Hermite-Gaussian mode spectra and topological charge
A. Volyar, E. Abramochkin, Yu. Egorov +2
We found that small perturbations of the optical vortex core in the Laguerre-Gaussian (LG) beams generate a fine structure of the Hermite-Gauss (HG) mode spectrum. Such perturbatio…
Digital sorting perturbed laguerre-gaussian beams by radial numbers via high order intensity moments
A. Volyar, M. Bretsko, Ya. Akimova +1
Thus, the results of our studies lie in developing and implementing the basic principles of digital sorting the Laguerre-Gauss modes by radial numbers both for a non-degenerate and…
Orbital angular momentum and informational entropy in perturbed vortex beams
A. Volyar, M. Bretsko, Ya. Akimova +1
We theoretically and experimentally investigated transformations of vortex beams subjected to sector perturbations in the form of hard-edged aperture. The transformations of the vo…
The avalanche instability of the orbital angular momentum in combined vortex beams
A. Volyar, M. Bretsko, Ya. Akimova +1
We presented a new method for measuring the squares of the amplitudes and phases of partial vortex-beams in a complex beam array in real time. The method is based on measuring the…
The mutual transformations of fractional-order and integer-order optical vortices
C. N. Alexeyev, Yu. A. Egorov, A. V. Volyar
We consider the problem of singular beams in optics as a part of the general questions of interactions, shaping and transformations of vortex states with fractional topological cha…
