Credit: ANU - An international team of scientists led by The Australian National University (ANU) researchers has developed a new robust type of light technology that could lead to cheaper and faster devices. The team created a laser that is immune to fabrication imperfections and external disturbances, such as unwanted light reflections and scatterings. The new technology behind the laser was enabled by recent fundamental discoveries in Physics and it could lead to a cost-effective miniaturisation of a wide range of light-based technologies. The developed lasers are so small that around a hundred of them could fit within a cross-section of a human hair. The new technology was developed by a team of scientists, led by ANU Professor Yuri Kivshar in cooperation with a group of Professor Hong-Gyu Park from Korea University. The technology could be crucial in the quest to replace current electronic circuitry with ultra-fast laser-based optical circuits.
