Profile:

Chen Xiangfei earned his Ph.D. from the Department of Physics and the National Laboratory of Solid State Microstructures, NJU. He then conducted research on fiber communication at Nanjing University of Posts and Telecommunications (then Nanjing Posts and Telecommunications College) and in August 2000, became an associate professor at the Department of Electronic Engineering, Tsinghua University.

In 2006, he joined the faculty of Nanjing University National Laboratory of Microstructures (then in preparation) and became a professor and a doctoral supervisor of the College of Engineering and Applied Sciences, NJU. He has played a part in establishing the Microwave Photonics Technology Laboratory and is a senior member of Chinese Optical Society and China Institute of Communications, the Optical Society of America, and Institute of Electrical and Electronics Engineers. He was one of the technical committee members of the 2011 International Meeting on Microwave Photonics (MWP).

Since 2006, Chen has made important academic achievements. (1) He has invented the semiconductor laser employing REC (Reconstruction-equivalent-chirp) technology and further developed monolithic integration array laser. The wavelength of the device has set a new national record. (2) He has developed a new type of bipolar optical CDMA coder that meets the international standards and also sets a record 1023 chip optical CDMA codec by using conventional devices. (3) He has proposed a way to realize long fiber Bragg gratings with splicing and employing REC technology.



Fields of Interest:

Semiconductor laser functions as an engine in optical communication systems is a crucial device. One focus of Chen’s research group is the DFB semiconductor laser and multi-wavelength array, including tunable laser, narrow linewidth laser, laser array with high wavelength accuracy, and their industrialization. At present, the group has successfully worked out the practical prototype of various semiconductor lasers and started its cooperation with HUAWEI, ZTE, HGTECH and other notable enterprises. It has also begun to conduct co-research with world-renowned research institutions such as Ghent University, Belgium, KTH Royal Institute of Technology, Sweden, and National Sun Yat-sen University, Taiwan, China.

The goal of the group is to develop a laser chip with its own intellectual property rights and drive forward its manufacturing in China. The group has also conducted considerable research on the systematic application of photonic integrated chips, for example, fast tunable lasers and photonic switching system. Besides, the group has gained impressive outcome from its research on microwave photonics and fiber sensing.
