Accurate Mode-Coupling Characterization of Low-Crosstalk Ring-Core Fibers using Integral Calculation based Swept-Wavelength Interferometry Measurement
Junwei Zhang, Jiangbo Zhu, Junyi Liu +8
In this paper, to accurately characterize the low inter-mode coupling of the weakly-coupled few mode fibers (FMFs), we propose a modified inter-mode coupling characterization metho…

80-Channel WDM-MDM Transmission over 50-km Ring-Core Fiber Using a Compact OAM DEMUX and Modular 4x4 MIMO Equalization
Junwei Zhang, Yuanhui Wen, Heyun Tan +8
8-OAM modes each carrying 10 wavelengths with 2.56-Tbit/s aggregated capacity and 10.24-bit/s/Hz spectral efficiency have been transmitted over 50-km specially designed ring-core f…

Orbital-angular-momentum mode-group multiplexed transmission over a graded-index ring-core fiber based on receive diversity and maximal ratio combining
Junwei Zhang, Guoxuan Zhu, Liu Jie +5
An orbital-angular-momentum (OAM) mode-group multiplexing (MGM) scheme based on a graded-index ring-core fiber (GIRCF) is proposed, in which a single-input two-output (or receive d…
