WebApr 25, 2012 · The effects of Kolmogorov thin-phase turbulence on the OAM channel capacity are quantified and it is found that increasing the turbulence leads to a degradation of the channel capacity. We describe an experimental implementation of a free-space 11-dimensional communication system using orbital angular momentum (OAM) modes. This … WebAug 9, 2024 · As the optical communication technology advances, vortex beam with orbital angular momentum (OAM) has gained wide attention due to its potential to significantly increase the channel capacity. Under the influence of atmospheric turbulence, there are still challenging problems in the OAM multiplexing system. To the best of our knowledge, in …
