Performance of 45-mode TILBA-ATMO for LEO-to-ground Turbulence Mitigation on turbulence emulation bench and on a 5-km ground-to-ground free-space testbed

With a more pressing demand for higher throughput in LEO-to-ground, FSOC offers a tailored solution with additional benefits such as more secure data transfer and no frequency allocation requirements. Cailabs' TILBA-ATMO, utilizing Multi-Plane Light Conversion (MPLC) technology, offers efficient turbulence mitigation for atmospheric communication. Here, a 45-mode system designed for Optical Ground Stations is demonstrated in a 5 km ground-to-ground link in different turbulence conditions. An in-depth study of the performances as a function of the different turbulence parameters is also conducted on an in-house designed turbulence emulation bench which copies a LEO-to-ground optical link.
