Researchers at the ARC Centre of Excellence for Ultrahigh bandwidth Devices for Optical Systems (CUDOS) have developed a method to selectively enhance or inhibit optical nonlinearities in a chip-scale device. Lead founder, PhD student Moritz Merklein, said the breakthrough was a fundamental advance for research in photonic chips and optical communications. “In optical communications systems optical nonlinearities are often regarded as a nuisance, which corrupts the flow of information. But at the same time there are many useful applications that harness these nonlinear effects. We showed that we can dramatically enhance the optical nonlinearity so that it can be made even more useful. On the other hand we showed that we can completely suppress the same nonlinear optical effects using the same principle. Importantly our experiments were performed in a photonic chip.”
