FLASH: Ultrafast beam quality characterization via spatial-to-temporal mapping
J. Qiu, Y. Xiong, X. Hua +2
Accurate and real-time monitoring of spatial beam quality has emerged as the absolute prerequisite for intelligent optical field regulation and advanced laser applications. However…
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…
Robust and Hyper-Efficient Multi-dimensional Optical Fiber Semantic Communication
Yuxuan Xiong, Ziwen Zhou, Jixing Ren +10
The growing demands of artificial intelligence and immersive media require communication beyond bit-level accuracy to meaning awareness. Conventional optical systems that focused o…
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…
