Highly efficient wideband and polarization-insensitive SMF-ARF coupling strategy with low back-reflection
Yi Su, Xuchen Hua, Bingyan Xue +3
We propose a lensed-fiber based coupling strategy for low-loss interconnection between single-mode fibers and anti-resonant fibers. By optimizing structural and geometric parameter…

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…
