Graphene could make internet one hundred times faster

The use of graphene in telecommunications could dramatically accelerate internet speeds by up to a hundred times, according to new research by scientists in the University of Bath's Department of Physics.

 

In a paper published in Physical Review Letters, researchers from the Centre for Graphene Science at the Universities of Bath and Exeter have demonstrated for the first time incredibly short optical response rates 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.

Lab work is never a barometer for what is achievable in real life. Bit of a nothing article if you ask me.

Is there anything the magical graphene cannot do?

It starts to sound awful similar to the "cloud" in software business.

Graphene DOES indeed do wonders, IBM show a transistor made of it... impressive switching speeds (I may be exagerating but it was around terahertz), problem is, to manufacture only one single transistor took them ages because it's not easy to produce it.

Great.  So this can be rolled out by when, and at what cost?

This is good news, the internet can always do with faster components :D

Cloud was just a rebranding of servers to make it sound less tech-y

 

Graphene will be heard of a lot more as researchers find real world uses for it :)

Perhaps I'm way too impatient, but it seems to me science isn't what it used to be :/

if its that strong could ya make spaceship hulls from it?

2018, for one million dollars.

Funny, no matter how fast they make it, ill never have it. ATT can't even get off their collective asses and fix the degraded cables in this part of the world, so we are stuck with WiMax wireless inet that you pay for 15 megs, and get 2.4. I wished I could move somewhere where eveything just works, but unfortunatly, thats not an option.

I'm presently convinced they're saving it for a rainy day, because too many things at the moment can cure cancer already. Indeed, cancer is being cured of people and people keep dying.

Oh yay... Graphene, the new wonder material! It can do this, it can do that, it can do EVERYTHING YOU COULD EVER IMAGINE!

Except for one teeny tiny little thing. Bring an actual product to market.

That's not true. You have dozens of books about it.

An actual product made of the stuff that actually delivers on some of the promises.
