TALK ABSTRACT
Since 1980’s, the capacity growth of digital fiber optic networks has been met by increasing single channel data rate (TDM) and wavelength multiplexing (WDM). The prevalent modulation format used was intensity modulation and direct detection (a.k.a. IMDD). Inter-symbol interferences in the fiber increases strongly with baud rate and thereby severely degrades signal quality and limiting reach in high bit rate TDM systems. In the early 2000’s, commercial serial 40G systems were not able to successfully deploy in the field. For the 10 years between 2007 and 2017, the commercial single channel data rate have increased 10 fold, from 40Gbit to the state of art 400Gbit per optical wavelength. The winning recipe is a coherent receiver with intra-dyne detection followed by high speed A/D sampling and digital signal processing. The combination enables the use of both the amplitude and phase of the optical electric field, allowing digital filters to compensate for linear impairments in the fiber. With access to the complete field information, advanced phase-modulated formats such as polarization-multiplexed QAM are ubiquitous, and is reducing the cost of a transmitted bit in all aspects of the fiber optic network. Combining advanced modulation techniques with large scale photonic integration, the state of art transmission system today, as implemented by Infinera, carries multi-terabits of data over a super channel. The development of the coherent DSP is at the heart of the Infinera Ottawa office.

SPEAKER BIO
Han Sun received the B.Eng. degree in electrical engineering and post-graduate degree in photonics and semiconductor lasers, both from the University of Toronto, Toronto, Ontario, Canada, in 1997 and 1999, respectively. From 2001 to 2009, he was employed with Nortel, Ottawa, Ontario, doing research on future optical transport systems. From 2003 to 2006, he was instrumental in the development of DSP algorithms which led to the World’s first commercial 40Gb optical modem employing Pol-Mux QPSK modulation format. He is currently with Infinera Canada, architecting the next generation transceivers targeting multiple Terabits per second.
He holds 20 granted US patents and 40 additional submissions. He has authored/co-authored over 39 technical journals papers and conference presentations. His publications have accumulated over 1200 citations. He has been a reviewer of IEEE Photonic Technology Letters and Journal of Lightwave Technology. His research interests include signal processing, receiver equalization, and error correction coding.
