Divergence-degenerate spatial multiplexing towards future ultrahigh capacity,low error-rate optical communications
文献摘要：
Spatial mode(de)multiplexiing of orbital angular momentum(OAM)beams is a promising solution to address future bandwidth issues,but the rapidly increasing divergence with the mode order severely limits the practically addressable number of OAM modes.Here we present a set of multi-vortex geometric beams(MVGBs)as high-dimensional information carriers for free-space optical communication,by virtue of three independent degrees of freedom(DoFs)including central OAM,sub-beam OAM,and coherent-state phase.The novel modal basis set has high divergence degeneracy,and highly consistent propagation behaviors among all spatial modes,capable of increasing the addressable spatial channels by two orders of magnitude than OAM basis as predicted.We experimentally realize the tri-DoF MVGB mode(de)multiplexing and data transmission by the conjugated modulation method,demonstrating lower error rates caused by center offset and coherent background noise,compared with OAM basis.Our work provides a potentially useful basis for the next generation of large-scale dense data communication.
