orthogonal-frequency-division-multiplexing (OFDM)
superchannel and optical multiband receiving method to
support a data rate higher than 200 Gb/s and to support
longer distance for direct-detection systems.
Papers 3-9 come from universities that are renowned for
research on optical transmission. In the third paper,“Spatial
Mode Division Multiplexing for High-Speed Optical Coherent
Detection Systems,”Professor William Shieh from the
University of Melbourne proposes using spatial mode division
multiplexing to increase transmission capacity. In the fourth
paper,“Exploiting the Faster-Than-Nyquist Concept in
Wavelength-Division Multiplexing Systems by Duobinary
Shaping,”Dr. Jianqiang Li from Chalmers University of
Technology presents a novel algorithm at the coherent
receiver that is based on digital signal processing and is
designed to tolerate strong filtering effects. In the fifth paper,
“Super Receiver Design for Superchannel-Coherent Optical
Systems,”Dr. Cheng Liu from Georgia Institute of Technology
presents a novel super-receiver architecture for
Nyquist-WDM superchannel coherent systems. This receiver
detects and demodulates multiple WDM channels
simultaneously and performs better than conventional
coherent receivers in Nyquist-WDM systems. In the sixth
paper,“Design of Silicon-Based High-Speed Plasmonic
Modulator,”Professor Yikai Su from Shanghai Jiao Tong
University proposes a silicon-based high-speed plasmonic
modulator. This modulator is based on a double-layer
structure with a 16 um long metal-dielectric-metal plasmonic
waveguide at the upper layer and two silicon single-mode
waveguides at the bottom layer. In the seventh paper,“Key
Technology in Optical OFDM-PON,”Professor Xiangjun Xin
from Beijing University of Posts and Telecommunications
proposes a novel optical access network based on OFDM. In
the eighth paper,“Compensation of Nonlinear Effects in
Coherent Detection Optical Transmission Systems,”Professor
Fan Zhang from Beijing University reviews two kinds of
nonlinear compensation methods: digital backward

propagation, and nonlinear electrical equalizer based on the
time-domain Volterra series. The last paper comes from a
telecommunication equipment manufacturer. In“Performance
Assessment of 1 Tb/s Nyquist-WDMPM-RZ-QPSK
Superchannel Transmission over 1000 km SMF-28 with MAP
Equalization,”Dr. Ze Dong from ZTE (USA) evaluates the
transmission performance of a 1 Tb/s (10 × 112 Gb/s)
Nyquist-WDM PM-RZ-QPSK superchannel over a widely
deployed SMF-28 fiber with and without MAP equalization.

Gee-Kung Chang received his PhD degree in physics from the University of
California, Riverside. He worked for 23 years at Telcordia Technologies
(formerly Bell Systems-Bell Labs, and then Bellcore), where he held research
and management positions, including director and chief scientist of optical
internet research, director of optical networking systems and testbed, and
director of optical system integration and network interoperability. Prior to
joining Georgia Institute of Technology, he was vice president and chief
technology strategist at OpNext Inc., an offshoot of Hitachi Telecom. Dr. Chang
is currently the Byers endowed chair professor of optical networking at the
School of Electrical and Computer Engineering, Georgia Institute of
Technology. He is an eminent scholar of the Georgia Research Alliance. He is
also co-director of the 100G Optical Networking Center at Georgia Tech. He
holds 56 U.S. patents and has co-authored more than 360 peer-reviewed
journal and conference papers. He was made a Telcordia Fellow in 1999 for
pioneering work in the optical networking project, MONET, and NGI. He was
made a fellow of the Photonic Society of Chinese-Americans in 2000. He is a
fellow of the IEEE Photonics Society and a fellow of the Optical Society of
America, recognized for his contributions to DWDM optical networking and
label switching technologies. He has served at many IEEE LEOS and OSA
conferences. He has been the lead guest editor for three special issues of the
Journal of Lightwave Technology, which is sponsored by IEEE LEOS and OSA.
Jianjun Yu (yu.jianjun@zte.com.cn) received his PhD degree in electrical
engineering from Beijing University of Posts and Telecommunications in 1999.
From June 1999 to January 2001, he was an assistant research professor at the
Research Center COM, Technical University of Denmark. From February 2001
to December 2002, he was a member of the technical staff at Lucent
Technologies and Agere Systems, Murray Hill, NJ. He joined Georgia Institute
of Technology in January 2003 as a research faculty member and director of
the Optical Network Laboratory. From November 2005 to February 2010, he
was a senior member of technical staff at NEC Laboratories America,
Princeton, NJ. Currently, he works for ZTE Corporation as the chief scientist on
high-speed optical transmission and director of optics labs in North America.
He is also a chair professor at Fudan University and adjunct professor and PhD
supervisor at the Georgia Institute of Technology, Beijing University of Posts
and Telecommunications, and Hunan University. He has authored more than
100 papers for prestigious journals and conferences. Dr. Yu holds 8 U.S.
patents with 30 others pending. He is a fellow of the Optical Society of
America. He is editor-in-chief of Recent Patents on Engineering and an
associate editor for the Journal of Lightwave Technology and Journal of Optical
Communications and Networking. Dr. Yu was a technical committee member
at IEEE LEOS from 2005 to 2007 and a technical committee member of OFC
from 2009 to 2011.
