It used to be known as the information superhighway – the fibre-optic infrastructure on which our gigabytes and petabytes of data whizz around the world at (nearly) the speed of light. And like any highway system, increased traffic has created slowdowns, especially at the junctions where data jumps on or off the system. Local and…

Researchers from the ARC Centre for Ultrahigh bandwidth Devices for Optical Systems (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. Radio frequency (RF) is a particular range of electromagnetic wave frequencies, widely…
