Simulation of vortex laser beams superposition propagation through a random optical environment

Vortex laser beams possessing an integer orbital angular momentum are promising for compaction of communication channels in the transmission of information by means of free-space optics. We consider vortex beams representing a superposition of the Laguerre-Gaussian modes with different indices, so they have a fractional orbital angular momentum. Such beams enhance the capabilities and improve the security of information transfer. We consider the propagation of vortex laser beams in a random medium based on the extended Huygens-Fresnel principle. To determine the modal composition of the considered beams under the conditions of random distortions we propose to use multichannel diffractive optical elements (DOE) matched with optical vortices.
