Optical Field Recovery in Jones Space

no code implementations22 Jun 2022 Qi Wu, Yixiao Zhu, Hexun Jiang, Qunbi Zhuge, Weisheng Hu

For cost-sensitive short-reach optical networks, some advanced single-polarization (SP) optical field recovery schemes are recently proposed to avoid chromatic dispersion-induced power fading effect, and improve the spectral efficiency for larger potential capacity.

Fast and accurate waveform modeling of long-haul multi-channel optical fiber transmission using a hybrid model-data driven scheme

no code implementations12 Jan 2022 Hang Yang, Zekun Niu, Haochen Zhao, Shilin Xiao, Weisheng Hu, Lilin Yi

The modeling of optical wave propagation in optical fiber is a task of fast and accurate solving the nonlinear Schr\"odinger equation (NLSE), and can enable the optical system design, digital signal processing verification and fast waveform calculation.

An Interpretable Mapping from a Communication System to a Neural Network for Optimal Transceiver-Joint Equalization

no code implementations23 Mar 2021 Zhiqun Zhai, Hexun Jiang, Mengfan Fu, Lei Liu, Lilin Yi, Weisheng Hu, Qunbi Zhuge

In this paper, we propose a scheme that utilizes the optimization ability of artificial intelligence (AI) for optimal transceiver-joint equalization in compensating for the optical filtering impairments caused by wavelength selective switches (WSS).

Low Complexity Component Nonlinear Distortions Mitigation Scheme for Probabilistically Shaped 64-QAM Signals

no code implementations21 Dec 2020 Yiwen Wu, Mengfan Fu, Huazhi Lun, Lilin Yi, Weisheng Hu, Qunbi Zhuge

We propose a degenerated hierarchical look-up table (DH-LUT) scheme to compensate component nonlinearities.

A Data-Fusion-Assisted Telemetry Layer for Autonomous Optical Networks

no code implementations24 Nov 2020 Xiaomin Liu, Huazhi Lun, Ruoxuan Gao, Meng Cai, Lilin Yi, Weisheng Hu, Qunbi Zhuge

For further improving the capacity and reliability of optical networks, a closed-loop autonomous architecture is preferred.
