Biography
I am an assistant professor in the School of Science and Engineering, The Chinese University of Hong Kong, Shenzhen (CUHK-SZ). I obtained my Ph.D. degree in Electronic Engineering, from The Chinese University of Hong Kong (CUHK), supervised by Prof. Hon Ki Tsang in 2018, and my Bachelor of Science degree in Information Engineering at Shanghai Jiao Tong University (SJTU) in 2014.
I am looking for motivated PhD/Master students, postdocs, and research assistants to work on integrated photonics and its applications. Please email me with your CV if you are interested in joining my group.
My research interests include three parts:
1. silicon photonics, integrated nonlinear photonics, quantum photonics, optical communications, optical sensing, and optical neural networks.
2. hybrid integration of two-dimensional (2D) materials onto the silicon photonics platform.
3. on-chip broadband frequency combs for applications on high-precision spectroscopy, and microwave generation, and symmetric breaking technique for random number generation, isolators, memories, and gyroscopes.
