High-Speed Multi-Dimensional Optical Field Measurement via MMF-MCF Spatial-Temporal Mapping Architecture
Yuxuan Xiong, Jingze Liu, Junjie Qiu +4
Wavelength and state of polarization constitute fundamental dimensions of optical fields. While simultaneous quantification of these parameters is critical, existing methodologies…
OAM modes characteristics analysis and low-loss transmission based on topological confinement
Yifan He, Xuchen Hua, Lei Shen +4
The topological confinement is a new mechanism that allows the transmission of cutoff orbital angular momentum (OAM) modes with negligible loss in ring-core fibers (RCFs) and provi…
Real-Time Distributed Optical Fiber Vibration Recognition via Extreme Lightweight Model and Cross-Domain Distillation
Zhongyao Luo, Hao Wu, Zhao Ge +1
Distributed optical fiber vibration sensing (DVS) systems offer a promising solution for large-scale monitoring and intrusion event recognition. However, their practical deployment…
Unsupervised super-spatial-resolution Brillouin frequency shift extraction based on physical enhanced spatial resolution neural network
Zhao Ge, Hao Wu, zhiyong Zhao +2
Spatial resolution (SR), a core parameter of Brillouin optical time-domain analysis (BOTDA) sensors, determines the minimum fiber length over which physical perturbations can be ac…
