Paolo Ghelfi


Paolo Ghelfi received the M.S. degree in electronics engineering from the University of Parma, Italy, in 2000. From 2001 he is with the National Laboratory of Photonic Networks of CNIT in Pisa, where he is now Head of Research. In 2008 he has been visiting scientist at KIST in Seoul, South Korea.
With the establishment of PhoTrix Srl (2006 – 2011), a spin-off company of CNIT and Scuola Superiore Sant’Anna, he experienced in the management of a company, dealing in particular with administration and production.
His research interests are in the field of optical communications, in particular in all-optical communication systems and digital photonics (pulsed laser sources, OTDM systems and all-optical processing, 3R all-optical regeneration, all-optical networking), and on WDM systems and networks (PMD compensation techniques, WDM-PON networks and access networks, reconfigurable optical networks). Recently he has been exploring the topic of microwave photonics, in particular for applications to radar systems (optical generation of ultra-stable RF carriers over wide frequency ranges, optical generation of wideband amplitude- and phase-modulated RF signals, precise optical sampling of RF signals, processing of optical samples for high-sampling-rate RF receivers, optical beamforming and true-time delay, radio-over-fiber) and to wireless communications systems (optical up- and down-conversion of reconfigurable wideband RF signals). From 2009 he acts as laboratory coordinator for the activities on microwave photonics.
Paolo Ghelfi has served as lecturer in several courses of international masters and Ph.D. programs held by Scuola Superiore Sant’Anna, Pisa, Italy.
He also serves as technical contact for collaborations between the LNRF and the several companies, as Selex ES, IDS SpA, Elettronica SpA, Consilium Italy, and Caliopa.
He has authored or co-authored 27 papers on International Journals, more than 85 papers on International Conferences, and 14 patents.
