Graphene promises femtosecond optical response for telecomms - #nanobio #g…

The Centre for Graphene Science at the Universities of Bath and Exeter has demonstrated for very short optical response rates using graphene, which could pave the way - they say - for a revolution in telecommunications. According to the University of Bath: Every day large amounts of information is transmitted and processed through optoelectronic devices such as optical fibres, photodetectors and lasers. Signals are sent by photons at infrared wavelengths and processed using optical switches, which convert signals into a series of light pulses. Ordinarily optical switches respond at rate of a few picoseconds - around a trillionth of a second. Through this study physicists have observed the response rate of an optical switch using "few layer graphene" to be around one hundred femtoseconds - nearly a hundred times quicker than current materials. Graphene is just one atom thic...
