Résumé: Due to the significant maturation of silicon photonics, this platform has become a viable technology for reducing the size, weight and power consumption of optical components for optical communication systems. Si photonics has also the potential to enable low-cost and high-volume production of CMOS-compatible photonic circuits suitable for monolithic integration with electronics. This technology allows for highly integrated photonic and electronic components, combines the functionality of conventional CMOS circuits with the significantly enhanced system performance of photonic solutions and fulfills the market needs for higher bandwidth and processing speed at lower power and cost. The talk will review design and fabrication of monolithically integrated circuits based on multimicroirng resonator structure for onchip interconnection networks, or network-on-chip (NoC), required for core-to-core and core-to-cache communications. The NoC not only must provide high performance in terms of latency and bandwidth (BW), but also must be energy efficient and integrated on the same platform. The current issue with the conventional electronic NoC is that, as the number of cores increases, the size of the electrical connections, the power dissipation, and the BW are becoming a bottleneck for the performance of the computing systems. Photonic solutions can alleviate this limitation, providing increased BW at low power consumption and no electromagnetic interference.

Note biographique: Stefano Faralli received the B.Sc. degree in physics from the University of Pisa, Pisa, Italy, in 2000, the M.Sc. degree in optical communications systems and networks from the Politecnico di Milano, Milan, Italy, in 2001, and the Ph.D. degree in telecommunications technology from Scuola Superiore Sant’Anna, Pisa, Italy, in 2006.
