Few-Mode Fiber Coupling under Atmospheric Turbulence

Free-space optical communication uses free space as a medium between transceivers, e.g., fibers. For longer propagation distances of the optical beam in free space, the atmospheric turbulence effects cannot be ignored. In this use case, we reproduce the experiments of Zheng et al. [Opt. Express 24 (2016)] to explore the atmospheric turbulence effects on the coupling efficiency between the free-space optical beam and few-mode fibers.
