NOVEL STUCTURES AND MATERIALS IN MICROSTRUCTURED POLYMER OPTICAL FIBRES. Last year we succeeded in fabricating the microstructured polymer optical fibres (MPOF). This work means that the fabrication constraints applying to similar glass fibres can be overcome, and entirely new types of structures can be investigated. As polymers can contain a much larger variety of dopants than glass the material properties of MPOF can also be fully exploited to develop new fibre functionalities. The combination ....NOVEL STUCTURES AND MATERIALS IN MICROSTRUCTURED POLYMER OPTICAL FIBRES. Last year we succeeded in fabricating the microstructured polymer optical fibres (MPOF). This work means that the fabrication constraints applying to similar glass fibres can be overcome, and entirely new types of structures can be investigated. As polymers can contain a much larger variety of dopants than glass the material properties of MPOF can also be fully exploited to develop new fibre functionalities. The combination of structural and material flexibility possible in MPOF offer the opportunity to radically redefine what is possible in microstructured fibres. It is these possibilities that we aim to explore in this project.Read moreRead less

Efficient interconnection of photonic components is the most critical research problem facing the photonics industry in its efforts for integration. In this project, interconnects for photonic systems will be developed, utilising a recently developed new class of fibres - microstructured optical fibres, which have been called 'the next generation' of optical fibres because of their ability to produce a variety of tailorisable optical effects. Specially designed and modified microstructured fibres will be developed to achieve efficient coupling from fibre to planar waveguide circuits, and to a range of photonic band gap devices that are currently being developed by the industry partner.Read moreRead less
Numerically Robust Extruder Die Design for Fabricating High-Quality Preforms for Microstructured Polymer Optical Fibres. Microstructural polymer optical fibres (mPOFs) were pioneered in Australia, are now comparable in performance (but much more versatile) than conventional polymer fibre, and are a highly attractive commercial option. Potential industrial applications envisage cost-effective preform fabrication as a key issue, with extrusion as the favoured route. This interdisciplinary project ....Numerically Robust Extruder Die Design for Fabricating High-Quality Preforms for Microstructured Polymer Optical Fibres. Microstructural polymer optical fibres (mPOFs) were pioneered in Australia, are now comparable in performance (but much more versatile) than conventional polymer fibre, and are a highly attractive commercial option. Potential industrial applications envisage cost-effective preform fabrication as a key issue, with extrusion as the favoured route. This interdisciplinary project benefits Australia by (i) extending and exploiting our research advantages in advanced photonics and computational rheology, (ii) providing the 'missing link' for large-scale mPOF production and positioning us to reap the economic benefits of this innovative technology, and (iii) providing computational techniques for rheological modelling that are applicable in diverse Australian industry sectors.Read moreRead less
Radiative Cooling Tuned to the Spectral and Directional Infra-red Properties of the Atmosphere. Growth in the demand for cooling in Australia is a main driver for new power stations while global warming adds to cooling and refrigeration needs. This project extends Australia's leading expertise in solar control using nanoparticles into the area of active and passive cooling, enabling cooling at night to temperatures well below ambient, with little or no power and low cost. 'Cool' will be stored ....Radiative Cooling Tuned to the Spectral and Directional Infra-red Properties of the Atmosphere. Growth in the demand for cooling in Australia is a main driver for new power stations while global warming adds to cooling and refrigeration needs. This project extends Australia's leading expertise in solar control using nanoparticles into the area of active and passive cooling, enabling cooling at night to temperatures well below ambient, with little or no power and low cost. 'Cool' will be stored simply for use the next day. Our systems also allow efficient and low cost water condensation from the atmosphere. They will be of major benefit to developing countries in warm climate zones. High value products will follow, from paints to low cost cooling technology with energy savings around 50% or more.Read moreRead less

Microstructured optical fibres have been described as the 'next generation' of optical fibres, because of their ability to produce tailorisable optical effects. Our success in producing these fibres in polymer was a world-first. This project will yield a fundamental understanding of the fabrication process, so that for any fibre design the optimal drawing conditions can be determined and maintained for extended draws. This will allow improved draw reproducibility and fibre uniformity so that commercial quality fibres can be produced at economic rates. We will establish quantitative relationships between drawing parameters and optical properties, thus developing optimal designs and production processes.Read moreRead less

One-step casting techniques will yield PMMA rods with arrays of internal channels which can be empty, or filled with different clear polymer. Polymer microstructured optical fibre (PMOF) suitable for high bandwidth communications is then produced by drawing. It is urgently needed for local communication networks in cars and buildings. Solid PMOF channels are new to this project, and should make PMOF easier to deploy. Nanoscale mapping of light transport modes and polymer defects will help validate channel designs.Read moreRead less
