Abstract:

Non-diffracting vortex beams are perspective information carriers for free space communications enabling an effective encoding, transfer and decoding of information. Adopting coaxial vortex superpositions, additional degrees of freedom of light are available to increase the density of the carried information. In this paper we present a novel decoding scheme motivated by a quantum state estimation technique capable of extracting full information encoded into an array of Bessel–Gauss beams.
