Putting stimulated Brillouin scattering to work: tailored optical-phononic interactions for on-chip signal processing. Light interacts with sound via a phenomenon called Brillouin scattering, an effect which is of major importance in modern nonlinear optics but is very difficult to control. Our pioneering project will open the door to low power optical devices and other diverse innovations that will support Australia's needs in defence and communications.

This project will investigate the interaction between electromagnetic waves and mechanical motion in structured media. Enhancing this interaction will improve a number of modern technologies, such as nano-scaled motors, traps for biological samples and optical wrenches. Modern fabrication techniques will link the electromagnetic and mechanical properties of media, so that the electromagnetic forces will greatly increase, making such devices able to manipulate larger objects. Structured materials can also change their properties dynamically, enabling material properties to be altered in real time. This mechanism will form the basis of advanced tunable components to control waves at visible, infrared, terahertz and microwave wavelengths.Read moreRead less

Metasurfaces are arrays of engineered dielectric and semiconductor nanoparticles, with extraordinary characteristics. The expected outcomes will lead to flat screens with resolution enhanced by 100 times and energy consumption reduced by half, as compared to current LC-based displays (e.g. LCD and LED). This novel technology will revolutionise the dimension and performance of displays and secure Australia's position in the billion dollar market of flat displays.

Auger-electron yields of medical radioisotopes. Large numbers of Auger electrons are emitted during the decay of many medical isotopes. Auger electrons have a short range and a strong ability to break chemical bonds. However no measurements of the number of Auger electrons per nuclear decay exist in the critical low energy regime. Calculated Auger yields are incomplete and inconsistent. Building on unique Australian expertise and instrumentation, and performing both calculations and measurements ....Auger-electron yields of medical radioisotopes. Large numbers of Auger electrons are emitted during the decay of many medical isotopes. Auger electrons have a short range and a strong ability to break chemical bonds. However no measurements of the number of Auger electrons per nuclear decay exist in the critical low energy regime. Calculated Auger yields are incomplete and inconsistent. Building on unique Australian expertise and instrumentation, and performing both calculations and measurements, his project aims to determine the number of Auger electrons per nuclear decay accurately for medical isotopes.
