Dr. Li has been working on the design, computer-aided modelling and simulation, processing, characterization and packaging of waveguide-based optoelectronic and photonic devices, such as semiconductor laser diodes, semiconductor optical amplifiers, super-luminescent light-emitting diodes, optical modulators, photo-detectors, wavelength division multiplexers, optical beam splitters, optical switch fabric, polarization controlled optical components, and the monolithic integration of these components. The application of these devices is mainly on fiber-optic communication systems and networks. Currently, Dr. Li is also actively exploring nanostructures such as surface plasmonic polariton (SPP) waves and SPP waveguides for advanced photonic devices, metamaterial structures for unidirectional wave propagation and optical cloaking, and randomly distributed nanostructures for super-resolution imaging and optical image transmission.



Xun Li received the B.S. degree from Shandong University, Jinan, China, in 1982, the M.S. degree from the Wuhan Research Institute of Posts Telecommunications, Wuhan, China, in 1984, and the Ph.D. degree from Beijing Jiaotong University, Beijing, China, in 1988.

In 1988, he joined the faculty of the Institute of Lightwave Technology, Beijing Jiaotong University, where he was a Professor. From 1993 to 1999, he was a Research Assistant Professor in the Department of Electrical and Computer Engineering, University of Waterloo, Waterloo, ON, Canada. In 1999, he joined the Department of Electrical and Computer Engineering, McMaster University, Hamilton, ON, where he is currently a Professor. In China, he was mainly involved in the development of III–V compound semiconductor laser diodes. He co-founded Apollo Photonics, Inc. and developed one of the company’s major software products “Advanced Laser Diode Simulator.” He is also an adjunct Professor with Huazhong University of Science and Technology, Beijing Jiaotong University, Minzu University, and Shandong University, China, respectively. He has authored or coauthored more than 300 journal and conference papers. He is also the author of a few book chapters on semiconductor DFB lasers and the book “Optoelectronic Devices: Design, Modeling, and Simulation”. His current research interests include design, modelling, simulation, and fabrication of integrated photonic and optoelectronic devices for fiber-optic communication systems and networks, and the design of nano-photonic devices. He has worked as a technical consultant for over 20 companies in the photonics industry over the past 30 years.

Dr. Li is a senior member of IEEE and OSA, and a member of SPIE. He is a licensed professional engineer in the province of Ontario, Canada.
