Abstract:

Micro/nano-scale materials and structures have attracted considerable attention in recent years for their unique advantages with a range of novel applications. In this talk, we will discuss techniques for achieving fabrication of sub-micron features and new optoelectronic applications with the integration of nanomaterials with these micro/nano-scale structures that my research group has been studying in recent years. With the femtosecond laser microfabrication and electric arc discharge technique, various micro-scale Mach-Zehnder interferometers have been realized, which serve as a backbone to achieve either planar waveguides working as opto-/micro-fluidic devices (lab-on-a-chip) or cylindrical waveguides in the form of microstructured fibers (lab-on-fiber) after integrating with different functional nanomaterials.  Taking advantage of specific physical, electrical, chemical, and biological responses, these devices and systems achieve microscale and nanoscale functionalities with high degree of integration and enhanced performance.

Biography:

Qiying Chen is a full professor in the Department of Physics and Physical Oceanography at Memorial University of Newfoundland. He received a Ph.D. degree in optics from Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences in 1996. He worked in Japan from 1996 to 2000, first as a lecturer in the Faculty of Engineering, Kyoto University and then as a researcher in the National Institute for Advanced Interdisciplinary Research. He was a postdoctoral researcher in the Photonics Group at the University of Toronto from 2000 to 2002. He worked as a research associate in the National Research Council of Canada (Integrated Manufacturing Technologies Institute) before joining Memorial University in 2004 as the Canada Research Chair in Photonics (Tier 2 until 2014). His research group at Memorial University has been working on ultrafast nano-photonics and laser applications with a focus on micro/nano-scale materials and structures for optoelectronic applications. He has about 180 publications and presentations in refereed journals and conferences and 6 patents.
