Alberto Paradisi, Ph.DVice President of Research & Development

OPTICAL COMMUNICATIONS APPLICATIONS

• Today advanced communication Technologies applications for the society• Industries, Bussiness/banks, Transportation, Household

and Global knowledge;• Optical communication research is fruit of combined

efforts in diverse disciplines:• Physics, photonics, electronics, algorithms and

networks;

HIGH CAPACITY COMMUNICATIONS LIMITATIONS

• Fiber capacity crunch• Today we have noticed 100 Tb/s single mode fiber hero

experiments;• Theoretical limit are around 200 Tb/s (mainly due

nonlinear effects);• CMOS ASICs limitations

• Processor frequency does not obey moore law since year 2000 (Core i7 runs at 3.5GHz)

• CMOS process today is 14nm, and the limitation is about 0.5 nm (two atoms layer);

TOMORROW DEMAND NEEDS AND TECHNOLOGIES

• Tomorrow advanced communication Technologies applications for the society• Medical diagnosis and treatment, traffic safety and

Internet of Things; • New solutions have to meet not just capacity

demand, but all economical perspective• More capacity, reduced cost/bit, increased energy

efficiency, smaller sizes;

HOT COMMUNICATION TECHNOLOGIES• To attend the high capacity demand, several

Technologies are promissing for the future of information technology• Integrated photonics (InP, Silicon photonics);• Integrated electronics (ASIC design); • Advanced optical subsystems;• Advanced Transmission/Reception; • Agile optical networks;

• WTON main goal is to discuss such technologies R&D&I
