    Joint Scheme of Dynamic Polarization Demultiplexing and PMD Compensation Up To Second Order for Flexible Receivers

    Joint Scheme of Dynamic Polarization Demultiplexing and PMD Compensation Up To Second Order for Flexible Receivers by Hengying Xu, Xiaoguang Zhang, Xianfeng Tang, Chenglin Bai, Lixia Xi, Wenbo Zhang, Hongjun Zheng

    Published 2017-01-01

    Polarization division multiplexing (PDM) doubles the bitrate of flexible transponders, whereas the joint effects of fast state of polarization (SOP) rotations, first-order polarization mode dispersion (PMD), and second-order PMD (SOPMD) would severely degrade the system performance. In this paper, w...

    Modulation Format Identification Using Graph-Based 2D Stokes Plane Analysis for Elastic Optical Network

    Modulation Format Identification Using Graph-Based 2D Stokes Plane Analysis for Elastic Optical Network by Lishan Yang, Hengying Xu, Chenglin Bai, Xinkuo Yu, Kangyoung You, Weibin Sun, Jiuhong Guo, Xiaoguang Zhang, Cailong Liu

    Published 2021-01-01

    We propose a graph-based modulation format identification (MFI) scheme for elastic optical network (EON), which exploits the trajectory information of the adjacent received symbols to identify six commonly-used modulation formats signals. A uniform grid is constructed in the first quadrant of two-di...
