MAIN RESEARCH PROJECTS (in reverse chronological order, starting from the most recent projects)
PhotoNext is the POLITO Inter-Dipartimental Center for Photonic technologies, focused on experimental and applied research in three key areas: optical fiber ultra-high speed communication systems, optical sensors and optical components for industrial applications.
Starting from 2010, thanks to a series of (ongoing) research contracts with Telecom Italia (TIM) Labs, he worked on next generation optical access networks (NG-PON2), in particular on WDM reflective PON, carrying out both experimental and theoretical works. The collaboration with TIM led to contributions to international standardization for NG-PON2 (ITU-T G.989.2) and to the ongoing standardization for the future generation PON, today (2018) indicated as High-Speed PON (HS-PON in G.sup.64 ).
Starting in October 2012, he was the Scientific Coordinator of the EU project FABULOUS, on FDMA-based optical access networks based on PON. The project involved both system level research, aimed at the optimization of optical transmission techniques, and component research, focused on silicon-photonic platforms integration.
In 2006-2011, he was the Coordinator of two consecutive EU projects titled POF-ALL (2006-2008, a STREP in FP7) and POF-PLUS (2008-2011, a STREP in FP6), both on low-cost transmission technologies on Plastic Optical Fibers (POF), an interesting and alternative solution to glass fibers in next-generation home networking and industrial automation applications. The activity on the POF area was very broad in terms of coordination, experimental activities and theoretical studies, and led to the first demonstration of a full-fledged pre-engineered prototype of a media converter at 1 Gbps running over SI-POF. On similar topics, he also participated in standardization activities in VDE/DKE and in the EU project ALPHA (2008-2010, an IP in FP7) and E-PhotonOne (2005-2008, FP6, where he acted as the coordinator of the WP on “Short Reach Communications”). This work led to contributions to international standards, and in particolar to the section dedicated to SI-PON in ITU-T G.9960 "Unified high-speed wireline-based home networking transceivers – System architecture and physical layer specification".
In 1998-2006 he actively participated in three consecutive PRIN projects (titled RINGO, WONDER and OSATE, for which he also acted as a research unit coordinator) on all-optical packet networks. This activity was mostly experimental, and led to different versions of network prototypes based on all-optical broadcast and select architectures.
From 1998 to 2003, he was in the core development team for the commercial software OptSim, one of the most advanced software for the physical layer simulation of optical transmission systems. Here, he focused on modelling of fiber nonlinear effects and on performance evaluation, with applications to long-haul DWDM systems. In particular, he focused on a nonlinear effect called “Parametric Gain” and on its impairments in transmission systems.
In 1997, he spent one year the Georgia Institute of Technology, Atlanta, as a visiting researcher in the OCPN group led by Prof. D. Blumenthal, where he worked in the realization of the MOSAIC optical network testbed, a prototypal version of wavelength routed optical networking.
During his PhD (1995-1998) he worked on optical transmission systems based on polarization modulation (POLSK), developing theoretical models for the evaluation of practical POLSK receivers, and a first experimental demonstration of a POLSK transmission systems.

On Google Scholar, he has an h-index equal to 30.
A full list of his publications can be found on the POLITO Publication repository.
He is currently an Associate Editor for IEEE/OSA Journal of Optical Communication and Networking (JOCN) for a second 3-year mandate (he started this activity in 2014).
He is (or was) member of the Technical Program Committees (TPC) of the following international conferences:

He is IEEE senior member from 2010.
DIDACTICAL AND ACADEMIC ACTIVITIES
Starting from 1998, Prof. Gaudino has always been involved in didactical activities at Politecnico di Torino, teaching courses in digital transmission, signal theory and optical communications. Starting from 2005, he was appointed as Coordinator of the Telecommunication Bachelor and Master degrees, and on the Master in Optical Communication and Photonic Technologies, again ad Politecnico di Torino. He is also active in professional lecturing for continuing education companies.
From 2006, he is member in the “Nucleo di Valutazione” (main internal evaluation body) at Politecnico di Milano. From 2007, he is the Director delegate at the POLITO Electronic and Telecommunication Department for external relations.
