Free-Space Turbulence Resistance Transmission with Multiple Quasi-Ring Airy Vortex Beams under Limited Receiving Aperture

Multiple quasi-ring Airy vortex beams (MQRAVBs) are generated to improve the transmission performance of orbital angular momentum (OAM) free-space optical (FSO) communication. Under turbulence strength D/r
0
=3.3 and receiving aperture of 0.03, the received power of MQRAVBs is improved by about 8 dB in the simulation, compared with traditional OAM beams when the cumulative probability is 0.1.
