From IT to black holes: nano-control of light pioneers new paths—8 April 2016

A research team at RMIT University has created a breakthrough chip for the nano-manipulation of light, paving the way for next gen optical technologies and enabling deeper understanding of black holes. Led by Australian Laureate Fellow, Professor Min Gu, the team designed an integrated nanophotonic chip that can achieve unparalleled levels of control over the angular momentum (AM) of light. The pioneering work opens new opportunities for using AM at a chip-scale for the generation, transmission, processing and recording of information, and could also be used to help scientists better understand the evolution and nature of black holes. “Our discovery could open up truly compact on-chip AM applications such as ultra-high definition display, ultra-high capacity optical communication and ultra-secure optical encryption. It could also be extended to characterise the AM properties of gravitational waves, to help us gain more information on how black holes interact with each other in the universe,” said Professor Gu.
