We demonstrate the beam steering capability of photonic crystal surface emitting laser via direct integration of diffractive structure. Large deflection angle and high transmittance y of laser beam can be achieved by optimization of surface meta-grating.

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.

Atmospheric turbulence-induced fluctuation on orbital angular momentum beam is experimentally evaluated by air convection generated from heated soldering irons. The performance is measured by the OAM mode spectrum and its temporal evolution.
