A unified resource-pool architecture for high-dimensional direct-detection optical communication
Jingze Liu, Zhijuan Gu, Xinyang Yu +12
Increasing optical communication capacity without proportionally increasing receiver complexity remains a key challenge for direct-detection links. Conventional systems typically a…
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…
Optical Semantic Communication through Multimode Fiber: From Symbol Transmission to Sentiment Analysis
Zheng Gao, Ting Jiang, Mingming Zhang +2
We propose and validate a novel optical semantic transmission scheme using multimode fiber (MMF). By leveraging the frequency sensitivity of intermodal dispersion in MMFs, we achie…
Real-time Event Recognition of Long-distance Distributed Vibration Sensing with Knowledge Distillation and Hardware Acceleration
Zhongyao Luo, Hao Wu, Zhao Ge +1
Fiber-optic sensing, especially distributed optical fiber vibration (DVS) sensing, is gaining importance in internet of things (IoT) applications, such as industrial safety monitor…
