Defan Sun
Biography
Dr. Defan Sun is a Postdoctoral Fellow at the Integrated Photonics Laboratory (IPL) under the supervision of Prof. Yating Wan at King Abdullah University of Science and Technology (KAUST). He earned his B.S. degree from the China University of Petroleum (UPC) in 2020 and his Ph.D. degree from the University of Chinese Academy of Sciences (UCAS).
Before joining KAUST, he worked as a Research Assistant at the Institute of Semiconductors, Chinese Academy of Sciences, for four years (2021-2025). During this time, he was a core member of several key research projects, including the National Key R&D Program of China, the National Natural Science Foundation of China (NSFC), and collaborative projects with Huawei Technologies Co., Ltd. His research focuses on the development and application of optical frequency combs based on mode-locked lasers. He has published 11 peer-reviewed articles (7 as first and corresponding authors) such as Photonics Research, Optics Express, and Optics Communications, etc.
He was recognised as the Outstanding Graduate of Shandong Province in 2020 and the Director's Scholarship of the Institute of Semiconductors, CAS in 2025.
