Title: Saving energy in information processing and communications with attojoule optoelectronics and optics

Speaker: Prof. David Miller Professor, Electrical Engineering, Stanford University


Information processing and communications is estimated to consume ~ 4.6 - 9% of all electricity, while internet communications traffic has been growing by factors of ~ 10 - 100 per decade. Reducing energy per bit processed or communicated is therefore essential if our use of information is to continue its growth. Most energy inside the internet and in information processing machines is dissipated in local electrical interconnects inside machines, not in long distance connections and not in logic operations themselves. The talk will discuss how emerging optics and sub-femtojoule optoelectronics could address issues of interconnect energy and density, for all distances from the edges of chips to connections between cabinets [1,2]. Key research areas include very close integration of photodetectors and transistors, very efficient beam couplers (for example, with nanophotonic techniques), exploring dense 2D optical interconnects enabled by silicon photonics technology, and "attojoule" optoelectronics generally. The prospect and goal is to reduce total energy for communication to ~ 10 fJ/bit for all distances up to ~ 10 m, in contrast to the current pJ/bit - 10's pJ/bit energies.

Bio of David Miller:

David Miller is the W. M. Keck Professor of Electrical Engineering and a Professor by Courtesy of Applied Physics at Stanford University. Following his B. Sc. in Physics from St. Andrews University, he received his Ph.D in Physics from Heriot-Watt University in 1979. Before moving to Stanford in 1996, he was with Bell Laboratories from 1981 to 1996, as a department head from 1987. His interests include nanophotonics, quantum-well optoelectronics, and optics in information sensing, interconnects, and processing. He has published more than 260 scientific papers, a quantum mechanics text, and 73 patents, was President of IEEE LEOS (now Photonics Society) in 1995, has received several awards, is a Fellow of APS, OSA, IEEE, the Electromagnetics Academy, the Royal Society of London and the Royal Society of Edinburgh, holds two Honorary Doctorates, and is a Member of the US National Academies of Sciences and of Engineering.
