A TECHNOLOGICAL breakthrough by University of Sydney scientists could lead to people downloading the latest movie in a few seconds or chatting with small, cheap, video systems.
The physicists have developed a revolutionary optical chip that could improve internet speeds to up to 100 times faster than Australia’s networks.
All traffic in the Internet is routed from source to destination by routers and switches which move the packets of data onto different parts of the network according to addresses contained within the data stream. The state-of-the-art technology in use today operates at 10gbps. The University of Sydney’s photonic switching technology holds the promise of being able to route and switch Internet traffic as optical signals at the rate of 640Gbps.
“This circuit uses the ’scratch’ as a guide or a switching a path for information - kind of like when trains are switched from one track to another - except this switch takes one picosecond to change tracks,” Prof Eggleton said of the technology developed over the past four years. “Currently we use electronics for our switching and that has been OK, but as we move toward a more tech-savvy future there is a demand for instant web gratification.”
He said the thumbnail-sized device could be commercialised within five years and used in countries such as Japan, which is “way ahead of Australia” in installing high speed fibre networks.
