Received a bachelor's degree from Huazhong University of Science and Technology in 2018. In September of the same year, he entered the State Key Laboratory of Regional Optical Fiber and New Optical Communications of Shanghai Jiaotong University to study for a doctorate. Under the tutelage of Professor Yi Lilin, he studied the direction of optical access network in optical fiber communication. It is a high-speed direct detection optical access system and a high-speed coherent optical access system. In the direct detection system, low-bandwidth photoelectric devices are used combined with low-cost DSP equalization technology to achieve high-speed and high-power budget optical access. In the high-speed coherent optical access system , build a low-cost frequency-locking system, realize point-to-multipoint (P2MP) optical access system architecture based on coherent detection, and solve the problem of high-speed burst detection of uplink signals in traditional time-division multiplexing optical access networks (TDM-PON).
Published a number of papers in important journals such as Journal of Lightwave Technology, Optics Letter, etc., and was awarded the National Optical Fiber Excellent Doctoral Student Award.
