Pilot Beam-Assisted Adaptive Compensation for Atmospheric Turbulence-Induced Phase Fluctuation on Beams Carrying Orbital Angular Momentum
We propose a pilot beam-assisted adaptive compensation method for atmospheric turbulence on beams carrying orbital angular momentum. Using the pilot beam having the same azimuthal index as the data beam considerably improves the compensation performances.
