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…
Multimode fiber speckle Stokes polarimeter
Yuxuan Xiong, Ting Jiang, Hao Wu +4
The detection of the state of polarization (SOP) of light is essential for many optical applications. However, it is a challenge for cost-effective SOP measurement due to the compl…
