Tiny laser gives big boost to high-speed data transmission




(November 5, 2013)  High-speed communication just got a turbo boost, thanks to a new laser technology developed at the University of Illinois that transmits error-free data over fiber optic networks at a blazing fast 40 gigabits per second – the fastest in the United States.

Milton Feng, the Nick Holonyak Jr. Chair in Electrical and Computer Engineering, demonstrated the tiny, fast device along with postdoctoral researcher Fei Tan, graduate students Mong-Kai Wu and Michael Liu, and Holonyak, who is an emeritus professor. The team published its results in the journal IEEE Photonics Technology Letters.

As computation shifts into the petascale and beyond, processor speeds have outstripped transfer speeds, creating a bottleneck and hindering applications. Anyone who has tried to stream video over a dial-up Internet connection knows that the fastest processor won’t help the file load quicker. And in the age of “big data” and cloud computing, there’s a lot of information swirling among servers.
