There are forty beaming faces staring up at me waiting for my next move. They giggle as I jump up and down, attempting to sing ‘with a moo-moo here’ from Old MacDonald’s Farm. I know I look ridiculous, but I’m far from caring. It’s 4pm in Cambodia and it’s a searing 40C. We are crammed into a tiny, non-air conditioned make-shift classroom in Phnom Penh. I’m trying desperately to keep their attention as they want to go and play.
Existing communications and computer architecture are increasingly being limited by the pedestrian speed of electrons moving through wires, and the future of high-speed communication and computing is in optics, experts say. The Holy Grail of results would be "wireless interconnecting," which operates at speeds 100 to 1,000 times faster than current technology. The new discovery, made by researchers at Oregon State University, the University of Iowa and Philipps University in Germany, has identified a way in which nanoscale devices based on gallium arsenide can respond to strong terahertz pulses for an extremely short period, controlling the electrical signal in a semiconductor. The research builds on previous findings for which OSU holds an issued patent.
