Graphene could lead to speeding up the internet by one hundred times

The use of graphene in telecommunications could dramatically accelerate internet speeds by up to a hundred times.
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.
Commenting on the report’s main findings, lead researcher Dr Enrico Da Como said: “We’ve seen an ultrafast optical response rate, using ‘few-layer graphene’, which has exciting applications for the development of high speed optoelectronic components based on graphene. This fast response is in the infrared part of the electromagnetic spectrum, where many applications in telecommunications, security and also medicine are currently developing and affecting our society.”
In the long term this research could also lead to the development of quantum cascade lasers based on graphene. Quantum cascade lasers are semiconductor lasers used in pollution monitoring, security and spectroscopy. Few-layer graphene could emerge as a unique platform for this interesting application.
