About
Pengbai Xu is a leading figure in the field of distributed fiber-optic sensing, with a particular focus on Brillouin-based curvature and shape reconstruction technologies. His research centers on developing innovative few-mode fibers and advanced Brillouin optical time-domain analysis techniques to overcome the fundamental limitations of conventional sensors. Xu’s major contributions include the creation of a bending-loss-resistant distributed Brillouin curvature sensor using an erbium-doped few-mode fiber (Er-FMF), which leverages erbium ion amplification to compensate for optical loss during tight bends, enabling accurate curvature measurements for radii as small as ~0.3 cm. He further advanced the field with a ring-core few-mode fiber (RC-FMF) design paired with differential pulse-pair Brillouin optical time-domain analysis (DPP-BOTDA), achieving distributed large-curvature sensing capable of reconstructing complex shapes, such as an asymmetric hump, via the Frenet-Serret algorithm. With his most-cited works accumulating over 33 citations, Xu’s research has significant implications for structural health monitoring, robotics, and biomedical applications, establishing him as a key innovator in smart sensing technologies.
