Abstract

The implementation of spatial multiplexing has become an area of great interest for free-space communication links, particularly for its use in last-mile links within larger optical networks. Light carrying orbital angular momentum (OAM) has emerged as a potential candidate that could be utilised for multiplexing independent channels. We will present measured inter-channel crosstalk for a set of 11-OAM modes propagating through 3m of slowly flowing water, similar to that found in oceanic flow conditions
