Abstract
Using the optical vortex beams (OVBs) can further improve the communication rate and spectrum utilization of the conventional space optical communication systems. In order to suppress the atmospheric turbulence effects in the space OVBs communication links, as well as to make the communication links simpler. We introduced the pin-like optical vortex beams (POVBs) that can dynamically self-focus during the free-space propagation. The POVBs have ability to counteract diffraction effects and atmospheric turbulence effects, and can maintain stable propagation with constant shape over long distances in the free-space. We theoretically analyzed the POVBs and experimentally demonstrated their stable propagation performance in the simulated atmospheric turbulence.
