Real-Time Visualization of the Spatiotemporal Dynamics of 3D Solitons
XinGe Liu, Chaoyang Geng, Yunhan Yu +3
Three-dimensional (3D) optical solitons bear far stronger relevance to multi-dimensional nonlinear dynamics prevalent in complex physical, chemical and biological systems than conv…
Effects of Random Birefringence in Multimode Fibers on Nonlinear Ultrashort Pulse Propagation
Chaoyang Geng, Hengyu Liu, Lixia Xi +2
Nonlinear pulse propagation in multimode fibers (MMFs) has attracted significant attention recently due to the rich spatiotemporal nonlinearities and promising applications. In pra…
Identifying modulation formats using integrated clustering algorithm
Wenbo Zhang, Jinmei Ye, Zixian Yue +4
Modulation format identification (MFI) is crucial in next-generation optical networks such as cognitive optical networks. An integrated-clustering-algorithm-based MFI scheme in a c…
A Effective Carrier Phase Recovery Method in Tigth Time-Packing Fast than Nyquist Optical Communication System
Peng Sun, Xiaoguang Zhang, Dongwei Pan +3
We propose a new scheme that combines polybinary transformaton and corrected-BPS to compensate noise for PDM-FTN-QPSK when its accelerated factor is 0.5,which has 3.3 dB OSNR gain…
Faster-than-Nyquist Nonlinear Frequency Division Multiplexing System
Xulun Zhang, Lixia Xi, Peng Sun +5
The faster-than-Nyquist nonlinear frequency division multiplexing system was first proposed, which provided 12.5% and 25% increase in spectral efficiency for the compression factor…
