5Gbps HG 0,1 and HG 0,3 optical mode division multiplexing for RoFSO
TL;DR: In this paper, a new optical mode division multiplexing (MDM) scheme for radio-over-free-space optics (Ro-FSO) networks was introduced by incorporating optical Hermite-Gaussian modes HG 0, 1 and HG 0 and 3 for transmitting two distinct 2.5Gbps data modulated on 10 GHz radio subcarriers.
Journal ArticleDOI
