A team of University of Otago / Dodd-Walls Centre scientists have created a novel device that could enable the next generation of faster more energy efficient internet. Their breakthrough results have been published in the world’s premiere scientific journal Nature this morning.
The internet is one of the single biggest consumers of power in the world. With data capacity expected to double every year and the physical infrastructure used to encode and process datareaching its limits there is huge pressure to find new solutions to increase the speed and capacity of the internet.
Principal Investigator Dr Harald Schwefel and Dr Madhuri Kumari’s research has found an answer. They have created a device called a microresonator optical frequency comb made outof a tiny disc of crystal. The device transforms a single colour of laser light into a rainbow of 160 different frequencies – each beam totally in sync with each other and perfectly stable. One such device could replace hundreds of power-consuming lasers currently used to encode and send data around the world.
