About
Ou Xu is a leading researcher in advanced fiber-optic sensing technologies, with a primary focus on distributed Brillouin sensors and interferometric curvature measurement systems. Their major contributions include pioneering the development of a bending-loss-resistant distributed Brillouin curvature sensor using an erbium-doped few-mode fiber, which leverages erbium ion amplification to compensate for bending-induced optical loss—enabling stable curvature detection even at extremely small radii (~0.3 cm). This work, published in 2021, has already garnered 19 citations, reflecting its significance in overcoming a critical limitation of conventional fiber sensors. More recently, Xu introduced a large measurement range curvature sensor based on an all-fiber Mach-Zehnder interferometer employing a triple-ring-core few-mode fiber, achieving enhanced sensitivity and dynamic range for structural health monitoring. This 2024 study, with 9 citations, demonstrates a simple yet robust SMF-TRCF-SMF sandwich structure. Xu’s innovations are driving progress in distributed sensing for aerospace, civil engineering, and smart infrastructure, making them a notable figure in the field of optical fiber sensors.
