Demonstration of an Air-Water Communication Link Through Dynamic Aerosol and Water Curvature when Considering the 2-D Modal Coupling of a Spatially Structured Beam

We experimentally investigate the 2-D modal power coupling of
$LG_{11}$
and
$HG_{11}$
beams under dynamic aerosol and water curvature, and demonstrate a 1-Gbit/s
$LG_{11}$
FSO link, having a penalty of ∼3-dB compared with no-effect cases.
