Professor Yuan and his groups at Nanyang Technological University of Singapore and Nankai University of China have been exploring novel applications of optical vortices for more than a decade. In this talk, he will introduce key technologies developed from optical vortices for radially polarized beams and modulation of surface plasmons in a microscopic configuration. The work is then extended to various applications associated with a novel high-performance multi-function optical microscope, combining optical microscopic imaging, bio-sensing and surface enhanced Raman Scattering (SERS) in a single microscope. The system is able to achieve wide-field super-resolved imaging of biological specimens, ultra-high sensitivity for molecule detection and real-time monitoring for reaction process of biological samples simultaneously, fulfilling the requirement of multi-parameter multi-function real-time in-situ measurement of biological samples.


Larry X.-C. Yuan received BEng and MEng degrees in optical engineering from Tianjin University, China, in 1985 and 1988, respectively, and PhD in physics from the University of London, King’s College, in 1994. Between 1994 and 1999, he was a research fellow with the Cavendish Laboratory, the University of Cambridge. Between 1999 and 2010, he was a faculty (tenured) in the School of EEE of Nanyang Technological University, Singapore. He is Chang Jiang Professor in the Institute of Modern Optics of Nankai University, and the Director of Key Laboratory of Optical Information Technical Science, Ministry of Education, China. His current work deals with optical vortices and their novel applications in plasmonic trapping, sensing, super-resolved microscopy and SERS, 3D imaging and display. He has published more than 180 journal papers in decent journals including Science, PRL, Lab Chip, APL, OL and others. He is an SPIE and OSA Fellow.
