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…

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…

Measurement of the vortex spectrum in a vortex-beam array without cuts and gluing of the wavefront

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…
