Optical Field Recovery in Jones Space
TL;DR: In this paper , a receiver of Jones-space field recovery (JSFR) is proposed to realize polarization diversity with SP carrier-assisted direct detection (DD) schemes, and the proposed receiver shows good tolerance to PMD since the optical field recovery is conducted before polarization recovery.

Investigation on the Dispersion Tolerance in Dual-drive MZM-based DAC-less Optical PAM4 Transmission
Kuo Zhang,Qunbi Zhuge,Haiyun Xin,Zhenping Xing,Rui Li,Meng Xiang,Sujie Fan,Lilin Yi,Weisheng Hu,David V. Plant +9 more
TL;DR: The chirp characteristics of the two PAM4 generation methods based on dual-drive MZM are investigated and prominent difference in transmission performance between the two methods is experimentally shown.
Channel Equalization and Phase Estimation for Reduced-Guard-Interval CO-OFDM Systems
TL;DR: In this article, the authors proposed a channel equalization and phase estimation scheme for reduced-guard-interval (RGI) coherent optical (CO) orthogonal frequency-division multiplexing (OFDM) systems.
Proceedings ArticleDOI
Advanced Optical Transmission Technologies for 5G Fronthaul
TL;DR: Recent advances in optical intensity modulation and direct detection transmission technologies for 5 G fronthaul applications including modulation, digital signal processing, faster-than-Nyquist signaling, DML based C-band transmission, and PON systems with DSP-free ONUs are reviewed.
