The research was presented at this month's IEEE International Solid-State Circuits Conference. The lead author is Jack Holloway '03, MNG '04, who completed his PhD in MIT's Department of Electrical Engineering and Computer Science (EECS) last fall and currently works for Raytheon. Co-authors include Ruonan Han, associate professor and Holloway's PhD adviser in EECS, and Georgios Dogiamis, a senior researcher at Intel.

The need for snappy data exchange is clear, especially in an era of remote work. "There's an explosion in the amount of information being shared between computer chips -- cloud computing, the internet, big data. And a lot of this happens over conventional copper wire," says Holloway. But copper wires, like those found in USB or HDMI cables, are power-hungry -- especially when dealing with heavy data loads. "There's a fundamental tradeoff between the amount of energy burned and the rate of information exchanged." Despite a growing demand for fast data transmission (beyond 100 gigabits per second) through conduits longer than a meter, Holloway says the typical solution has been "increasingly bulky and costly" copper cables.
