Biography
Prof. Zhaoyu Zhang received his B.S. and M.S. degree 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 in University of California, Berkeley as a postdoctoral fellow in 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 a team of “Nano OptoElectronics Lab (NOEL)”. In 2015, he and his team moved to Chinese University of Hong Kong, Shenzhen. In 2016, he was approved to set up Key Labortary of Semicoductor laser, Shenzhen and be the director. His main achievements including 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 20 referred papers on renowned journals including Nature Communications, Advanced Materials, Physics Review Letters, Optica, Photonics research, Optics Letters, Applied Physics Letters, etc. Please refer to NOEL web for detail information and student openings
