Breakthrough technology to improve cyber security

With enough computing effort most contemporary security systems will be broken. But a research team at the University of Sydney has made a major breakthrough in generating single photons (light particles), as carriers of quantum information in security systems. The collaboration involving physicists at the Centre for Ultrahigh bandwidth Devices for Optical Systems (CUDOS), an ARC Centre of Excellence headquartered in the School of Physics, and electrical engineers from the School of Electrical and Information Engineering, has been published today in Nature Communications.

CUDOS is funded by the Australian Research Council under the Centres of Excellence Program , with further support from our seven constituent universities, fifteen partner investigators, and the New South Wales State Government.

Australia-Israel collaboration achieves first nanophotonic topological system


An international team of researchers from the Australian Research Centre of Excellence CUDOS (Centre for Ultrahigh bandwidth Devices for Optical Systems) at the University of Sydney and Technion - Israel Institute of Technology have demonstrated the first topologically protected waveguiding in a silicon nanophotonic platform.


CUDOS researcher wins Sydney University Alumni Medal


Congratulations Dr Tomonori Hu, winner of the Rita and John Cornforth Medal at last night’s Alumni Awards ceremony held in the Great Hall of the University.


Breaking of tiny light pulses observed in a nanophotonic chip for the first time


The pulse splitting phenomenon, called soliton fission, could lead to novel rainbow light sources used in compact optical communications systems and lab-on-a-chip spectroscopic tools for portable medical diagnostics.


Nanomaterial to drive new generation of solar cells


Australian physicists have discovered radical new properties in a nanomaterial which opens new possibilities for the fabrication of highly efficient thermophotovoltaic cells, which could one day harvest heat in the dark and turn it into electricity.
