SID Student Chapter Seminar: “Optical Sensing with Microstructured Fibers” – Yan-qing Lu
Monday, August 29, 2011 / 11:00am-12:00pm
Prof. Yan-qing Lu
College of Engineering and Applied Sciences, Nanjing University, China
Optical fiber is a micron-scale element with lights trapped in its core. People have attempted to incorporate “microstructures” into fibers for years. A successful example is the photonic crystal fiber (PCF). With the fast progress in micro- and even nano-fabrication techniques, we have more freedom to design and fabricate various “Microstructured fibers”. The microstructure induces “optical resonance” or “phase matching”, which are normally sensitive to environmental conditions. On the other hand, optical fiber is a perfect light transmission line with industry standard input/output connections. As a consequence, the combination of fiber and microstructure would give promising applications in optical sensing. In this talk, I will introduce our recent work on various fiber-optic sensors, including PCF index/ temperature sensors with multi-beam interference, liquid crystal cladding fiber for pressure sensing, transflective nano-wire grid fiber sensor, microfiber coil resonator and micro-fiber probe FP/FBG sensors.
Yan-qing Lu received his Ph.D. degree from Nanjing University, China in 1996. He is currently a professor at the College of Engineering and Applied Sciences, Nanjing University. He is the author or co-author of ~80 peer-reviewed papers with over 800 citations. He also holds over 20 patents or pending patents. His research interests include fiber optics, liquid-crystal and nonlinear optics. He was a visiting research scientist in Prof. S. T. Wu’s group in CREOL, UCF during 2003-2005. He is an associate editor of OSA’s Optical Materials Express.
