New class of light wave discovered—29 January 2016

Physicists at the ARC Centre of Excellence for Ultrahigh bandwidth Devices for Optical Systems (CUDOS), in collaboration with the University of Toronto and the University of York, have made a remarkable discovery that opens up future applications in many areas such as in precision laser surgery, imaging devices, and ultrafast computing and communication technology. Observed in nature, the soliton (a wave that maintains its shape as it travels over long distances), was first discovered in 1834. Until now, it was generally assumed that everything that could be known about solitons had already been discovered. Now CUDOS researchers have discovered an entirely new class of optical soliton called ‘pure-quartic solitons’. During their experiments they found that pure-quartic solitons have remarkable properties compared to conventional ones—they have a different shape and can be more energetic than previously reported solitons. They also evolve in a different way and occur at different power thresholds. These properties can turn them into excellent candidates to be used in a number of important applications which the CUDOS team are currently exploring.
