Abstract

Spatial-mode multiplexing (SMM) increases free-space optical link capacity, but is impaired by atmospheric turbulence. We derive the optimal modes for SMM in turbulence, showing they achieve higher capacity than other mode sets. We review methods for modal (de)multiplexing and MIMO signal processing in SMM links.
