IQ Skew and Imbalance Estimation for Coherent Point-to-Multi-Point Optical Networks
Ji Zhou, Jianrui Zeng, Haide Wang +4
Coherent point-to-multi-point (PtMP) optical network based on digital subcarrier multiplexing (DSCM) has been a promising technology for metro and access networks to achieve cost s…
Pilot-Based Key Distribution and Encryption for Secure Coherent Passive Optical Networks
Haide Wang, Ji Zhou, Qingxin Lu +5
The security issues of passive optical networks (PONs) have always been a concern due to broadcast transmission. Physical-layer security enhancement for the coherent PON should be…
Capacity Limitation and Optimization Strategy for Flexible Point-to-Multi-Point Optical Networks
Ji Zhou, Haide Wang, Liangchuan Li +3
Point-to-multi-point (PtMP) optical networks become the main solutions for network-edge applications such as passive optical networks and radio access networks. Entropy-loading dig…
Non-Integer-Oversampling Digital Signal Processing for Coherent Passive Optical Networks
Haide Wang, Ji Zhou, Jinyang Yang +5
Beyond 100G passive optical networks (PONs) will be required to meet the ever-increasing traffic demand in the future. Coherent optical technologies are the competitive solutions f…
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…
Highly efficient acousto-optic modulation using nonsuspended thin-film lithium niobate-chalcogenide hybrid waveguides
Lei Wan, Zhiqiang Yang, Wenfeng Zhou +9
A highly efficient on-chip acousto-optic modulator, as a key component, occupies an exceptional position in microwave-to-optical conversion. Homogeneous thin-film lithium niobate i…
Sorting OAM modes with metasurfaces based on raytracing improved optical coordinate transformation
Zhibing Liu, Jiahui Zou, Zhaoyu Lai +4
Optical coordinate transformation (OCT) has attracted widespread attention in the field of orbital angular momentum (OAM) (de)multiplexing or manipulation, but the performance of O…
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…
