The project aims to generate and investigate several novel families of self-stabilising optical pulses by using a unique fibre laser we recently devised. By developing the associated theoretical models, the team will transform conceptual and experimental knowledge of nonlinear physics, providing deep insights into fibre lasers and the pulses they can emit. The expected outcomes are a complete understanding of entirely novel families of optical pulses, and of the degree to which the energy required to generate these pulses can be reduced. Reducing this energy means that these pulses can perform the same function at lower power, which will enable the emergence of new applications that will play powerful roles in the 21st-century economy.Read moreRead less
Deep-ultraviolet light source by frequency doubling of blue or green light for disinfection. Current ultraviolet light sources are inefficient and often bulky. By an alternative approach, in which the wavelength of blue or green light is halved, this project will design and build compact, efficient sources of ultraviolet light, which can be used for disinfection and sterilization. Such devices can be fabricated by Australian industry in Australia.

Dual nanoparticles to distinguish between right and left biomolecules. This project aims to enhance the sensitivity of optical activity to ultralow molecular concentration samples. Optical activity is a commercially available technique used to distinguish chemically identical and morphologically different biomolecules (enantiomers). Unlike other scattering techniques, near-field enhancing of optical activity has not been achieved, thus limiting these measurements to high molecular concentrations ....Dual nanoparticles to distinguish between right and left biomolecules. This project aims to enhance the sensitivity of optical activity to ultralow molecular concentration samples. Optical activity is a commercially available technique used to distinguish chemically identical and morphologically different biomolecules (enantiomers). Unlike other scattering techniques, near-field enhancing of optical activity has not been achieved, thus limiting these measurements to high molecular concentrations. There is evidence indicating that optical activity can be enhanced using dual nanoparticles (ie small particles with the same response to electric and magnetic fields). This project aims to advance our understanding of these dual nanoparticles and experimentally implement their use to enhance optical activity.Read moreRead less
