Graphene photonics breakthrough promises fast-speed, low-cost communications

Swinburne researchers have developed a high-quality continuous graphene oxide thin film that shows potential for ultrafast telecommunications.

Associate Professor Baohua Jia led a team of researchers from Swinburne's Centre for Micro-Photonics to create a micrometre thin film with record-breaking optical nonlinearity suitable for high performance integrated photonic devices used in all-optical communications, biomedicine and photonic computing.

"Such a laser patternable highly nonlinear thin film, about one hundredth of a human hair, has not been achieved by any other material," Professor Jia said.
