ABSTRACT: The ever increasing demand for communication services and the tremendous growth of the Internet are driving the development of high-capacity optical networks. With the evolution of optical systems from 10 Gb/s to higher bit rates (40 Gb/s and beyond), new technical challenges arise. Suitable signal processing plays a key role to increase the total capacity per fiber and the attainable distance without compensation/regeneration. Transform-based signal processing performed in both optical and electrical domains will be presented, showing different applications for high-speed optical networks. All-optical architectures for multiplexing/demultiplexing, encoding/decoding, data compression and denoising will be given. Furthermore, Optical Orthogonal Frequency Division Multiplexing (O-OFDM) techniques will be described, for the mitigation of transmission impairments in coherent and direct detection transmission systems.
SPEAKER. Michela Svaluto Moreolo received the M.Sc. degree with honours in electronics engineering and the Ph.D. degree in telecommunications engineering from University Roma Tre, Rome, Italy, in May 2003 and April 2007, respectively. From January 2007 to December 2008 she has held a Postdoctoral position at the Applied Electronics Department of University Roma Tre. She has been a visiting researcher at the ‘Christian Doppler Laboratory of Surface Optics', Institute of Semiconductor and Solid State Physics, Johannes Kepler University, Linz, Austria, from January 2004 to July 2004. Since January 2009, she is with the Optical Networking Group of CTTC as a Post-Doc researcher. Her research interests are in the field of optical signal processing for high-speed large-capacity optical networks. Her research activity has been focused on the design and modeling of planar lightwave circuits, multiplexer/demultiplexers, encoder/decoders for IP routing, and slow-light devices for all-optical buffering in transparent optical networks. Currently, her studies are directed towards optical OFDM and optical transmission techniques.
