Record Capacity-Reach of C band IM/DD Optical Systems over Dispersion-Uncompensated Links
Haide Wang, Ji Zhou, Jinlong Wei +5
We experimentally demonstrate a C band 100Gbit/s intensity modulation and direct detection entropy-loaded multi-rate Nyquist-subcarrier modulation signal over 100km dispersion-unco…
The third- and fourth-order orbital angular momentum multiplexed amplification with ultra-low differential mode gain
TianJin Wen, Shecheng Gao, Wei Li +6
In this Letter, a ring-core erbium-doped fiber (RC-EDF), with two-layer erbium-doped structure, supporting up to the fourth-order orbital angular momentum (OAM) mode is designed an…

In this paper, we propose a faster-than-Nyquist (FTN) non-orthogonal frequency-division multiplexing (NOFDM) scheme for visible light communications (VLC) where the multiplexing/de…
Capacity limit for faster-than-Nyquist non-orthogonal frequency-division multiplexing signaling
Ji Zhou, Yaojun Qiao, Zhanyu Yang +2
Faster-than-Nyquist (FTN) signal achieves higher spectral efficiency and capacity compared to Nyquist signal due to its smaller pulse interval or narrower subcarrier spacing. Shann…
