To reduce the power consumed by the internet an international team of researchers (Germany, Austria, New Zealand, Russia) has created a device called a microresonator optical frequency comb made of 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. They expect the devices to be incorporated in sub-oceanic landing stations where all the information from land based fibres is crammed into the few sub-oceanic fibres available in less than a decade, perhaps within a few years. To develop the device for the telecommunications industry they are working with a company in New Zealand…read more. TECHNICAL ARTICLE
