High power orbital-angular-momentum (OAM) beam has dominant advantages in capacity increasing and data receiving for free-space optical communication systems at long distance. Utilizing coherent combination of beam array technique and helical phase approximation by piston-phase-array, we have proposed a generation system of high power novel beam carrying OAM, which could overcome power limitation of common vortex phase modulator and single beam. We have experimentally implemented a high power…

Transverse spatial modes of light offer a large state-space with interesting physical properties. For exploiting these special modes in future long-distance experiments, the modes will have to be

Twisted light communication through turbulent air across Vienna

This work experimentally transmits classical information encoded in the intensity patterns of 16 OAM mode superpositions through 3 km of strong turbulence over the city of Vienna and shows that in this method the relative phase between two modes is transmitted in a stable way.
