About

Dr. Yongkang Gong is researcher and lecturer at the Faculty of Computing, Engineering and Science in the University of South Wales. His main expertise in nanophotonics lies in novel optoelectronic devices/systems utilizing nanophotonic technologies such as plasmonics, metamaterials, silicon photonics, and fiber gratings. He graduated in 2005 with Bsc in Physics and obtained a PhD in Optics from the Chinese Academy of Science in 2011. During his PhD study, he worked on novel plasmonic integrated devices and because of his outstanding academic performance, he was awarded ‘Daheng’ Scholarship in 2009, ‘Western Student’ Scholarship in 2010, and Chinese Academy of Science Dean Reward in 2011, respectively.
Upon completion of his PhD, he joined Wireless and Optoelectronics Research and Innovation Centre (WORIC) at the University of South Wales. He works closely with industry and academic partners and has successfully delivered several projects at WORIC. He worked on a Lomox funded project on highly efficient photonic-crystal-enhanced organic light emitting diode from 2011. After that he worked as co-investigator and project manager in an A4B grant on a novel semiconductor optical wavelength conversion technology (patent US20140016933) through cooperation with Oclaro, University College London and University of Southampton. He then worked on fast electro-optic plasmonic modulator for laser wireless communication in unmanned aerial vehicles funded by Airbus.
In 2015 Dr Gong was appointed by USW as researcher (permanent appointment) and lecturer of BSc Optoelectronics for Communication. He has been active in establishing connections and partnerships with a number of relevant industrial firms for the purpose of collaborative research. He has authored and co-authored more than 40 high impact journal papers with WoS H-index of >20 and number of citations exceeding 1500. He has presented several invited talks to major international photonic conferences and was session organizer of IEEE 3M-Nano 2016 on “Plasmonic Nanophotonics and Metamaterials” . He currently supervises 3 PhDs as first supervisor and has supervised >10 MSc student projects. He has also been active in promoting the public understanding of science and research of photonics by giving Christmas lectures to local primary school students.

Experience

My research interest mainly includes novel photonic materials, nanophotonics technologies (plasmonic metamaterials, photonic crystals, 2D materials etc), LED/OLED lighting, laser technologies and novel integrated photonic devices/systems for high capacity/speed telecommunication, chemical/medical biosensing, and high efficiency lighting etc. I am experienced in full-wave 2D/3D optical design/simulations (FDTD, FEM, RCWA, Matlab programming) and laser/E-beam nanofabrications and characterization.
