Now, a circuit '60 times faster than current broadband'

MELBOURN: Scientists have developed what they claim is a small scratch on a piece of glass, which will make the Internet nearly 60 times faster and give users unlimited, error-free access anywhere in the world.

"This is a critical building block and a fundamental advance on what is already out there. We are talking about networks that are potentially up to 100 times faster without costing the consumer any more.

"The scratched glass we have developed is actually a Photonic Integrated Circuit. This circuit uses the 'scratch' as a guide or a switching path for information, kind of like when trains are switched from one track to another, except this switch takes only one picosecond to change tracks.

"This means that in one second the switch is turning on and off about one million times. We are talking about photonic technology that has terabit per second capacity," lead researcher Ben Eggleton at the University of Sydney said.

Though the initial demonstration has shown that it is possible to achieve speeds 60 times faster than many current networks, with further development, the process is likely to produce even faster results, according to the researchers.

"Currently we use electronics for our switching and that has been OK but as we move toward a more tech-savvy future there's demand for instant web gratification. Photonic technology delivers what's needed and, importantly, what is wanted," he said.

The University of Sydney has developed the scratch in collaboration with the Technical University of Denmark and financial support from Australian Research Council.
