The project aims to apply laser light to reduce the temperature of electronic circuits. This aims to greatly suppress electronic noise, and enable a new class of technologies for future telecommunication systems. By developing new techniques to confine light, electric fields and vibrations at sub-micron scale on a silicon chip, devices such as ultralow noise amplifiers, clocks and radio frequency receivers will be realised, along with ultra-efficient optical modulators. In future, these technologies could reduce energy consumption and improve reliability in telecommunication networks. They could improve the range of satellite communication, robustness of GPS against cosmic radiation, and performance of surveillance systems such as radar and sonar.Read moreRead less
A portable sensor for explosives. The National Research priority, safeguarding Australia, recognises that there is a real threat of terrorism and the need to protect Australians at home and abroad. Although there is often talk of dirty bombs, and biological and nuclear terrorism, the most easily sourced weapon of the terrorist is still the conventional explosive. The ability to detect trace amounts of explosives is therefore required. This means that there is a real need for a portable detection ....A portable sensor for explosives. The National Research priority, safeguarding Australia, recognises that there is a real threat of terrorism and the need to protect Australians at home and abroad. Although there is often talk of dirty bombs, and biological and nuclear terrorism, the most easily sourced weapon of the terrorist is still the conventional explosive. The ability to detect trace amounts of explosives is therefore required. This means that there is a real need for a portable detection system with the ability to reliably sense a specific explosive selectively at low concentrations. This project concerns the development of a new handheld sensor that has the potential to increase the nation's security.Read moreRead less
