About

Baijie Xu is a leading researcher in the field of optical fiber sensors, with a particular focus on femtosecond-laser-inscribed fiber Bragg gratings (FBGs). Their work has significantly advanced the fabrication technologies and sensing applications of these devices, which are prized for their compact size, high sensitivity, and multiplexing capabilities. Xu’s most-cited paper, a comprehensive review on the topic (2021, 176 citations), has become a key reference for researchers exploring UV-free, direct-write grating methods. In a standout contribution, Xu demonstrated the first orthogonal single-mode helical Bragg gratings created in fiber cladding for vector bending measurement (2022, 17 citations). This novel sensor, inscribed using a femtosecond laser, enables precise two-dimensional bending detection—a major step forward for structural health monitoring and robotics. By overcoming the limitations of conventional UV-based fabrication, Xu’s work has opened new pathways for robust, high-performance sensors. Their research continues to shape the future of smart sensing technologies, making them a pivotal figure in modern photonics and fiber optics.
