dr. Sante Andreoli, Art Group, ‘ICT for Infomobility’
Abstract: Art is an electronic industry that develops apparata, systems and solutions for the transportation market, e.g.: automotive, infomobility, motor sport F1, space, railways and agricolture applications. The description of themes and developments in these markets, the role played by the technologies, and especially ICT, will be shown. A section of the talk will be devoted to the operative model, with emphasis to the management of the technological innovation and its integration and synergy with the industrial processes.

Abstract: 100 Gigabit Ethernet is actually demanding for next generation optical networks. Since the transition between 1 to 10 GbE mainly involves cost and power consumption reduction, the jump toward 100GbE must take care of physical, technological and transmission issues. Electronic components and ICs are pushed to their limitation in terms of bandwidth and power requirement and, at the same time, optics are still in their early stage. Novel material, techniques and approaches must be reviewed in order to understand real 100 GbE perspectives. Within such framework, the state of the art for 100 Gbit/s transponder will be analysed and their suitability for 100 GbE discussed. At the same time, different technological solution including Electrical Time Division Multiplexing (ETDM), Wavelength Division Multiplexing (WDM), Optical Time Division Multiplexing (OTDM), and Polarization Division Mutiplexing (PDM) will be addressed in single and hybrid configuration. Modulation formats will be also considered together with transmission impairments as a function of the link characteristics. Finally, latest experimental results will be reviewed, compared, and discussed.

Abstract: In the last two decades the telecom transport market has experienced the evolution from the “digital electro-optic” to the “analog photonic” technology. It is very likely that the next decade will see the transition from the “analog photonic” to the “digital photonic”, in which a ultra-high bit-rate telecom signal will be processed at very low cost preserving the features of scalability in bit-rate and wavelengths which were brought in by analog photonics, meanwhile providing the necessary immunity from noise and transmission impairments which are typical of digital systems. Photonic digital processing of high speed optical signals will also open new applications where fast computation speed is required as in the field of optical interconnect inside mainframes, in clusters of servers inside data rooms and in applications of cloud computing among remotely located servers, with advantages in terms of throughput, wiring density, latency, and power consumption. Even if appropriate technologies are not yet mature enough, a feasibility demonstration of the digital photonic processing potential is mandatory to drive the future technology evolution. Here we will present recent results at the leading edge in the international scenario, on the realization of the basic blocks of photonic digital processing as all-optical logic gates, switches and flip-flops and more complex subsystems enabled by such basic blocks, as optical combinatorial networks to carry out full addition, comparison, counting, analog-to-digital and digital-to-analog conversion. The reported implementations are based on semiconductor and waveguide devices here considered as possible technological choices due to their integrability, and stability features.
