Biography:

Ansheng Liu received the B. S. degree in semiconductor physics from Sichuan University, Chengdu, China, in 1982; M. S. degree in semiconductor physics from Zhongshan University, Guangzhou, China, in 1985; Ph. D. degree in physics from the University of Aalborg, Aalborg, Denmark, in 1992.

    He is currently a Principal Engineer with the Corporate Technology Group, Intel Corporation, Santa Clara, California, where he is developing silicon photonic devices and photonic integrated circuits for high speed optical interconnect and communications. He is one of the key contributors to Intel’s recent technology breakthroughs in fast silicon optical modulator and continuous-wave Raman silicon amplifier and laser. Before joining Intel in 2000, he worked at NASA Ames Research Center, Moffett Field, California; the National Institute of Standards and Technology, Gaithersburg, Maryland; and at the University of Aalborg, Denmark as an assistant professor. His interests include nonlinear optics of nanostructures, near-field optics, opto-electronics, and photonics. He has authored or co-authored more than 100 publications in these fields and contributed to more than 45 patents. He was awarded Intel Achievement Award and Visiting Professorship at Sichuan University, Chengdu, China, in 2005. He has been a reviewer for various prestigious journals. He is the member of OFC/NFOEC 2007 and 2008 program committee. He has also been an invited speaker for various international conferences.
