Investigation on the scintillation reduction of elliptical vortex beams propagating in atmospheric turbulence
Atmospheric optics Free-space optical communication
2013/7/3
We numerically investigate the scintillation index of an elliptical vortex beam in both modest turbulence and strong turbulence. Numerical simulations are realized with random phase screen sc...
Experimental investigation on the scintillation index of vortex beams propagating in simulated atmospheric turbulence
Experimental investigation scintillation index vortex beams propagating simulated atmospheric turbulence
2013/7/3
The scintillation index of vortex beam in simu-lated atmospheric turbulence is experimentally investigated.The fluctuation of the intensity can be effectively reduced by vortex beams. In particular, t...
Beam-spreading and topological charge of vortex beams propagating in a turbulent atmosphere
Vortex beams Turbulent atmosphere Beam-spreading Orbital angular momentum
2013/7/3
We theoretically and experimentally investigate the beam-spreading of a vortex beam propagating in a turbulent atmosphere. It is found that the vortex beam is less affected by turbulence than a non-vo...
Polarization Changes of Partially Coherent Electromagnetic Vortex Beams Propagating in Turbulent Atmosphere
