1The 50Gbps Si Photonics Link A research milestone from Intel Labs 2Today’s Agenda Today’s News and Impact Mr. Justin Rattner Intel Chief Technology Officer Senior Fellow, VP Director of Intel Labs Technology Overview Dr. Mario Paniccia Intel Fellow Director, Photonics Technology Lab QA to Follow Presentation 3Today’s news: 50Gbps Si Photonics Link ? First silicon photonics data link with integrated lasers – Research milestone using Hybrid Silicon Lasers – “Concept vehicle” runs at 50Gbps, scalable to 100Gbps, 400Gbps, …Tbps ? Integrating our previous Si photonic building blocks – Devices that emit, manipulate, combine, separate and detect light ? Brings volume Si manufacturing to optical communications Could make optical communications affordable for any compute platform, revolutionize apps architectures 4Why Photonics? Copper wires reaching physical limits ? ~10 Gbps or higher becoming challenging ? Distance/speed tradeoff shortens lengths Alternative: Transmit data over optical fiber ? Much further reach at any given speed ? Multiple signals can travel on one fiber ? Thin light = easy cable management Challenge: optical signaling technology is expensive 5A Half Century of Innovation Lasers Countless apps 50 years 1960 Today ? Practical usages not known upon invention ? Laser has impacted industries from medicine to manufacturing to entertainment and more ? All long distance communications driven by lasers Costs limits use of optical for everyday devices First Laser (Ted Maiman) 6A Half Century of Integration First Silicon IC (Noyce and Kilby) Silicon Billions of Transistors ~50 years ? We have gone from 2 transistors to 2 billion ? This “Moore’s Law” scaling has led to transformative technologies ? Mainframes - Servers - PCs - Laptops - Handhelds ? Internet, e-commerce, social media ? 1959 Today Silicon manufacturing has made this all possible 7Bringing Si Manufacturing to Optical Comms Optical CommunicationsSi Manufacturing Very high bandwidth Long
