Dear all Access Indians, Using miracle material graphene in telecommunications could dramatically make internet a hundred times faster, a new study has found. Researchers from the Universities of Bath and Exeter have demonstrated for the first time incredibly short optical response rate using graphene, which could pave the way for a revolution in telecommunications. 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 thick, but remarkably strong. Scientists have suggested that it would take an elephant, balanced on a pencil to break through a single sheet. Already dubbed a miracle material due to its strength, lightness, flexibility, conductivity and low cost, it could now enter the market to dramatically improve telecommunications, researchers said. "We have seen ultra-fast optical response rate of optical switch, using few layer graphene, which has exciting applications for the development of high-speed optoelectronic components based on graphene," lead researcher Dr Enrico Da Como said. I hereby invite Access indians to share the latest data on the highest internet speed per second along with the comments on this article.
