Emerging Signal Processing Techniques in Optical Communications

Abstract
The end of the last decade in optical communications was marked by an expectation of emergence of all-optical networks, similarly to the decade before that was focused on coherent optical communication systems. The former of the time-periods neglected the power of digital signal processing (DSP), as well as its low-cost. The latter neglected the robustness of non-coherent modulation formats, in addition to – the low cost of modulation and detection apparatuses. The past twenty years of research into the physical layer have amassed a great body of knowledge on the fiber optic channel physics which should not be disposed off of all too easily. More likely, it is a judicious combination of the all-optical and the DSP techniques which will define the surviving optical communication systems. In this presentation, I will review recent activity at UCSD in all-optical and electronic signal processing, including parametric amplifiers’ enabled all-optical signal processing (e.g. 100ns all-optical delays), as well as high spectral efficiency telecom systems availed by network edge electronic processing.

Nikola Alic
Nikola Alic graduated from the School of Electrical Engineering (Dept. of Optoelectronics and Laser Technology) at the University of Belgrade, Serbia in 1998, with a BS degree in Electrical Engineering. After graduation, he worked as a junior scientist at "Vinca" Institute of Nuclear Sciences in Belgrade, Serbia, investigating pulse compression and solitonic propagation in nonlinear fiber arrays. Dr. Alic received his Ph.D. degree from the University of California, San Diego in 2006. He is currently a research scientist at the California Institute for Telecommunications and Information Technology, UC San Diego. His research interests are optical fiber communications, communication theory and nonlinear fiber optics.
