We will create a new composite glass providing strong fluorescence which fully exploits the high transmission of glass in the mid-infrared. When combined with emerging rare earth ion transitions and precise excitation processes, this project will help solve an important problem in optics; that the overall efficiency and power produced from deep mid-infrared light sources is not sufficient for all industries. The primary outcome will be a series of robust fibre-based gain modules suitable for high power and very short optical pulses in the mid-infrared. These light sources will beneficially impact medicine, defence, sensing and manufacturing providing excellent opportunities for increasing Australian productivity and global competitiveness.

Silicon-germanium-carbon - a novel opto-mechanic material for optical micro-electromechanical systems. Evolving from past black-and-white images, through present red-green-blue multi-spectral capability, future remote imaging systems promise spectroscopic functionality across much broader wavelength ranges in a low-cost system. However, the high cost of multiple materials and technologies for each specific spectral band limits them to high-cost industry sectors.

Evolving from past black-and-white images, through present red-green-blue multi-spectral capability, future remote imaging systems promise spectroscopic functionality across much broader wavelength ranges in a low-cost system. However, the high cost of multiple materials and technologies for each specific spectral band limits them to high-cost industry sectors. This project proposes a simple, low-cost, single material technology based on silicon-germanium-carbon thin films for mechanical and optical applications from ultraviolet to long-wave infrared, enabling widespread application of spectroscopic imaging to multiple fields extending from climate change research, through resource exploration, to cancer detection, and aerospace/defense.Read moreRead less

This project intends to identify and analyse the structural vulnerabilities of the emerging ‘smart grid’ for electricity supply. The smart grid integrates a cyber network into the existing power network. Although the smart grid enables the integration of more renewable energy sources and contributes to an environmentally sustainable society, the network structure can introduce new vulnerabilities that may cause large cascading failures and lead to catastrophic blackouts. The project aims to establish a quantitative framework to analyse smart grid structural vulnerability. Furthermore, innovative reinforcement and defence strategies will be proposed that could reduce the risk of large blackout and build a more robust smart grid.Read moreRead less
