Researchers from the ARC Centre for Ultrahigh Bandwidth Devices for Optical System (CUDOS) in The University of Sydney’s Australian Institute for Nanoscale Science and Technology have made a breakthrough achieving radio frequency signal control at sub-nanosecond time scales on a chip-scale optical device.

The breakthrough, which could unlock the bandwidth bottleneck faced by wireless networks worldwide, was published in the high-impact journal Optica

CUDOS Director and Australian Laureate Fellow, Professor Benjamin Eggleton, who co-authored the paper with PhD candidate, Mr Yang Liu, said the technology would lead to next-generation improvements to wireless networks.

“We expect the applications of this work will happen within a decade in order to provide a solution to the wireless bandwidth problem. Such a system will be crucial not only to safeguard our defence capabilities, it will also help foster the so-called wireless revolution—where more and more devices are connected to the wireless network,” Professor Eggleton said. “This includes the internet of things, fifth generation (5G) communications, and smart home and smart cities."
