Biographical Sketch

I received my B.S. degree from the Department of Optics in Shandong University in 1993, and then my M.S. degree in Solid State Physics in the Institute of Crystal Materials, Shandong Unviersity in 1996. My M.S. thesis advisor is Professor Dong Xu. After a one year stay as a Ph.D. student with the Departement of Physics at the University of Virginia (UVa), I started the Ph.D. thesis research in system aspects of optical fiber communications in the ECE Department of the UVa in 1997. My Ph.D. thesis advisor Professor Maite Brandt-Pearce . I received my Ph.D. degree in 2001.

Since August 2000, I have worked as optical engineer, senior engineer, and consulting engineer in fiber optic communications systems vendors such as PhotonEx, Corvis, and Tyco Telecommunications, mainly on modeling (including experimental validation), simulation and design of 10-40 Gb/s long-haul DWDM subsystems and terrestrial, under-sea, and sub-sea systems which forms the backbone of the Internet. In August 2006, I left industry and joined the ECET Department of the Minnesota State University Mankato as a tenure track assistant professor. In August 2009 I was promoted to the rank of associate professor. I was awarded tenure in 2011. I was promoted to full professor in 2013. I have been the Chair of the ECET Department since Summery 2016.

During my one year leave in 2010, I was a principal engineer at Oclaro Inc, working on system level modeling and design of 40G and 100G DP QPSK/16-QAM transponders. During the 2013 academic year I was on sabbatical working as a consulting DSP engineer for Oclaro Inc. on high speed modules. From 2011 to 2012, and during 2014, I was a consulting engineering for Oclaro working on 100 Gb/s DP/16-QAM transceivers. From 2012 to 2015 I was a technology consultant for Micropoint Bioscience Inc working on signal processing algorithm development and prototype for Point-of-Care-Testing (POCT) systems. From August 2016 to June 2019 to I was a technology consultant for NeoPhotonics Corporation on modeling, simulation, and design of Silicon Photonics (SiP) modulators and semiconductor optical amplfiers (SOAs).

Recently as a technology consultant, I played one of the leading roles in the design of NeoPhotonics SiP modulators. In March 2019 we presented record high speed SiP modulator with commercial foundry at 400Gb/s and beyond at SPIE Silicon Photonics XIV (part of SPIE Photonics West 2019). We presented our SiP modulator operating at 85Gbaud 16QAM and 64Gbaud 64QAM with commercial foundry, practical pulse-shaping, and real-time DSP at OFC 2019 (top score paper), again a record! In our recently published invited IEEE/OSA Journal of Lightwave Technology paper, we presented the real-time operation of SiPh modulator enabling 1 Terabits per second (Tbps) transmission.
