Fighting terrorism and crime is one of the most important and difficult tasks that requires substantial human and technological resources. This project will help to address this enormous problem by developing a new optical sensor technology for the detection and identification of traces of chemicals, explosives, drugs and biological agents. It will develop a laboratory prototype of this sensor that is expected to have superior sensitivity and operational capabilities. Thus it will noticeably contribute to practical law enforcement, air quality and environmental monitoring, counter-terrorism, air safety, border security and customs service. It will also lead to further development of nano-optics and nanotechnology in Australia. Read moreRead less

Development of a Novel and Quantitative Approach to Phase Imaging with Applications to Functional Nanomaterials. This project will improve and apply an innovative approach to obtaining phase information from electron microscopy images, currently being commercialised by IATIA Ltd. We will develop the approach so that it is fully quantitative, even at the nanoscale, and explore the effect of experimental parameters such as beam coherence, aberrations, specimen contamination and diffraction.

This project will improve and apply an innovative approach to obtaining phase information from electron microscopy images, currently being commercialised by IATIA Ltd. We will develop the approach so that it is fully quantitative, even at the nanoscale, and explore the effect of experimental parameters such as beam coherence, aberrations, specimen contamination and diffraction. We will apply the method to both physical and molecular nanomaterials, including a new class of self-organising molecules. Phase imaging can visualise the structures, polarities, charge and conductivity distributions in these materials and so assist in the development of new materials and devices.Read moreRead less

This project will focus on developing and understanding further the recent invention of the Fresnel fibre, which is designed to overcome diffraction from the end of an optical fibre. More sophisticated designs and combinations will allow arbitrary shaping of the optical field exiting an optical fibre for numerous applications. The physical basis for such phenomena to be realised is the efficient degree of coherent scattering possible in air-material fibre such as air-silica photonic crystal fibres. In conjunction advanced characterisation techniques will be developed.Read moreRead less

These will include novel grating-array based 2-D DFB lasers and filters in rare-earth doped planar waveguides. Novel etching techniques to be used to enhance index contrast, as well as to characterise such devices, will be developed based on our recent observation of hydrogen-enhanced etching of glass. Such methods could potentially be applicable to not only photonic technologies but also semiconductor lithography of oxides.Read moreRead less
