Nanophotonic metamaterials as anti-counterfeit devices in Australian banknotes. This project will demonstrate the application of novel materials as the basis for next generation security features on banknotes. Such elements play a key role in maintaining the integrity of Australia's currency since they present a significant barrier to counterfeiting.
Targeted light - optical mode control at the nanoscale. Nanophotonics provides a path for controlling the interaction of light and matter at the nanoscale. Using spatially tailored laser beams to address nano-particles, this project aims to create new approaches for specifically targeting light with nano-scale precision, which has valuable potential applications in biosensing and communications.
A versatile optical wavelength and mode switching device for future telecommunication networks. This project will develop a next generation switching device for future fibre optical communication networks that will divide their information among several modes of specialty fibre. This device will be a key component for allowing network operators to move to these novel mode-multiplexed networks in order to overcome the looming capacity crunch.

The laser sources generally do not have simple (Gaussian) distributions. The applicant has recently developed a model, describing free propagation of complex (non-Gaussian) laser beams. This project seeks to develop a comprehending model for laser beams propagation through complex optical systems. The effects of various optical elements will be defined employing a novel method known as SAFE (Stable Aggregate of Flexible Elements) which is a compromise between geometrical and physical optics. Applying this model to micromachining and optical data storage (ODS), which need high beam quality (low divergence and good focussibility), enable accurate predictive capability critical to the optimisation of micromachining and ODS designs.Read moreRead less

Frozen linear and nonlinear light. Frozen light refers to the observation that light inside particular media can be much brighter than outside it, essentially because it bounced around many times before leaving. Such light has many advantages which have applications in optical signal processing, lasers, and in other optical devices. Until now frozen light has only been studied in a small range of geometries and only at low intensities. In this fundamental research project we will investigate fr ....Frozen linear and nonlinear light. Frozen light refers to the observation that light inside particular media can be much brighter than outside it, essentially because it bounced around many times before leaving. Such light has many advantages which have applications in optical signal processing, lasers, and in other optical devices. Until now frozen light has only been studied in a small range of geometries and only at low intensities. In this fundamental research project we will investigate frozen light, its generation and its properties at low and high intensities, systematically, and we will assess how it can be harnessed for potential applications.Read moreRead less

We have recently made significant advances in development of all-solid-state intracavity Raman lasers generating multiwatt average powers in the near infrared and (by frequency doubling) visible spectrum, with important applications in biomedicine and remote sensing. A new generation of Raman crystals, especially tungstates, offer superior optical, mechanical and thermal properties, promising high Raman gains and choice of Stokes frequency shift. The project will investigate a range of key issues for these materials including control of the Stokes wavelength, associated polarisation control, and pump-resonator configurations giving maximum Raman laser power and efficiency. The project will lead to state-of-the-art source technology with outstanding prospects for commercialisation and practical application.Read moreRead less
