Advanced modulation formats are proposed and analysed for next generation optical networks. The new evolving optical networks data rates of 100G and above require real time analog-to-digital conversion followed by real time digital signal processing. This is in order to allow increased spectral efficiency and full compensation of amplitude and phase distortion imposed by the optical channel in such high bitrates. Various approaches are presented, including discrete multi-tone and optical OFDM.

Prof. Dan Sadot received his B.Sc., M.Sc., and Ph.D. (Summa Cum Laude) from the Ben Gurion University of the Negev, Beer Sheva, Israel, all in Electrical and Computer Engineering, in 1988, 1990, and 1994, respectively. During 1994-1995, he was a Post-Doctorate associate in the Optical Communication Research Laboratory at the Department of Electrical Engineering of Stanford University. His Ph.D. studies were supported by the Clore scholarship, and his post-doctorate was supported by both the Fulbright and the Rothchild scholarships. In 1995, Dan Sadot joined the ECE department at Ben Gurion University where he started a new research program in Optical Fiber Communications. In 2001 he was appointed as associate professor, and since 2009 he is a full professor. Prof. Sadot current activities include Digital Signal Processing in Optical Communications, Coherent Detection, Optical OFDM, and dynamic WDM networks.
Currently, Prof. Sadot is the Chairman of the ECE Department of the Ben Gurion University. Prof. Sadot was the founder and CTO of three startup companies: TeraCross (in 1999), Xlight Photonics (in 2000), and MultiPhy (since 2007).
