Biography

Prof. Zhaoyu Zhang received his B.S. and M.S. degrees in Applied Mechanics from University of Science and Technology of China, Hefei, China, in 1998 and 2001 respectively. He received Ph.D. degree from California Institute of Technology, Pasadena USA in 2007 in Electrical Engineering. From 2008 to 2011, he worked at University of California, Berkeley as a postdoctoral fellow in the College of Chemistry, with a joint appointment with Lawrence Berkeley National Laboratory. From 2011 to 2015, he worked in Peking University as an Associate Professor and led the team of “Nano-OptoElectronics Lab (NOEL)”. In 2015, he and his team moved to The Chinese University of Hong Kong, Shenzhen. In 2016, he was approved to set up the Shenzhen Key Laboratory of Semiconductor lasers and be the director. His main achievements include the first demonstration of red-emission photonic crystal lasers, wavelength-scale micro-lasers with physical size smaller than 1 micron, microfluidic microlasers based on dye materials, as well as the first demonstration of photonic crystal lasers directly grown on silicon substrates. He has published more than 30 peer-reviewed papers on renowned journals including Nature Communications, Light: Science and Applications, ACS Photonics, Advanced Materials, Nanophotonics, Physics Review Letters, Optica, Photonics research, Optics Letters, Applied Physics Letters, etc.
