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) and Technion - Israel Institute of Technology have demonstrated the first topologically protected waveguiding in a silicon nanophotonic platform. The research findings published in Physical Review Letters are a key advance towards the development of robust optical circuits that has the potential of enabling large-scale optical integration and quantum information processing.

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.
