Dang, Anhong is a professor in the Department of Electronics, School of EECS. He received the B.S. degree in electrical engineering from Fudan University in Shanghai, China, in 1990, and the M.S. and Ph.D. degrees in the information and communications engineering from Xi’an Jiaotong University, Xi’an, China, in 1997 and 2001, respectively. He served as a research assistant with the Institute of Electron and Machine, Electronic Ministry of China from 1990 to 1994. He was a visiting scholar at Huawei Technologies Co., Ltd., Shenzhen, China, from 1998 to 1999 while working towards the Ph.D. degree. From 2001 to 2003, he was a Postdoctoral Fellow with the Department of Electronics, Peking University, Beijing, China. In 2003, he joined the Peking University faculty. His current research interests are wireless optical communications (WOC), quantum devices, optical signal detection, and optical networks.

Dr. Dang has published more than 80 research papers, and most of them are published in top-tier conferences and journals, such as IEEE Trans., Opt. Express, Appl. Opt., GLOBECOM，ICC, and ECOC. He has authorized 6 China invention patents and a software copyright. He has served in the Technical Program Committee of various international conferences including ICACT, OWCC. He is serving as an editor of BINGGONG ZIDONGHUA, is also in the Editorial Board of Advances in Wireless Communications and Networks, Engineering Physics.

Dr. Dang has more than 20 research projects including 973 programs, 863 project, NSFC, etc. His research achievements are summarized as follows:

1) Light transmission over atmospheric turbulent channels. He proposed a phase screen generation algorithm based on fractal theory, and investigated the long term beam spread and the beam wander based on the generalized anisotropic non-Kolmogorov power spectrum. He also addressed theoretically and experimentally in turbulence-induced fluctuations of the overall parameters in polarizations, including Stokes parameters, azimuth, ellipticity, and DOP.

2) Wireless optical communication system. He proposed a novel polarization-multiplexing system for WOC, and studied performance of coherent BPSK Systems using phase compensation. He also developed a coherent system at 10Gbps and BER of 1×10-8.

3) Quantum devices. He developed a self-adapting and small FADOF, and an excited state FADOF working at the optical communication wavelength is realized. He also successfully applied FADOF to the WOC, and compared the systematic property of the FADOF and IF receivers.

4) Optical networks. He proposed a novel coherent OCDMA for multi-user access WOC, where the laser is modulated by PSK and demodulated without the help of local laser. He also proposed an inter-satellite optical multiple access scheme, which combines SDMA and CDMA, and significantly reduces stringent requirements of simultaneous acquiring and tracking multiple platforms.
