Australia is set to reap commercial benefits nationally and internationally from new developments in the highly competitive domain of microtechnology. In this project, a group of Australia's leading researchers propose an innovative combination of two exciting fields of scientific research. Microfluidics is the manipulation of minute quantities of liquids in microscopic channels, while photonics is the generation, transmission, detection and analysis of light as a means to convey, collect and process information. The marriage of these two fields promises the development of novel, high performance tunable devices for sensing, biotechnology and telecommunications.Read moreRead less
Fibre amplifiers and lasers with enhanced and novel functionality based on novel fibre fabricated by chelate modified chemical vapour deposition.

One Step Pre-forms for Microstructured Polymer Optical Fibre. The pre-form rods this project yields will enable polymer optical fibre technology, just as suitable glass pre-forms enabled today's optical fibre. One-step casting techniques will yield PMMA rods with arrays of internal channels which can be empty, or filled with different clear polymer.

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

We aim to develop chalcogenide glass films for fabricating integrated waveguide magneto-optic (MO) devices as a radical alternative to the use of crystalline MO materials that have proven difficult to manufacture in integrated form. Using our ultra-fast pulsed laser deposition (UFPLD) technique we will produce a wide range of chalcogenide glass compositions through combinatorial materials synthesis and assess them for magneto-optic activity. UFPLD will also be used to deposit high optical quality films for device prototyping. We will design and fabricate prototype MO components which are essential, but currently unavailable, for use as optical isolators in integrated optics.Read moreRead less

The project proposes to create a novel technology to measure soil moisture. Accurate knowledge of soil moisture profiles at high resolution is important for sustainable land and water management including efficient irrigation scheduling and cropping practices. A passive multi-band soil moisture-measuring radiometer at L-, Ku- and Ka-bands is proposed. The radiometer comprises a three-band shared aperture antenna array, a receiving electronics, a digital controller and a data logger. The array antenna comprises dual polarised stacked patch elements. Beamforming networks form agile beams to scan the ground. Sensitive radiometer receivers apply brightness temperature downscaling for high resolution. The high-resolution passive radiometer would revolutionise airborne soil moisture monitoring by removing the mechanically steerable bulky and heavy scanheads.Read moreRead less

This project aims to design and develop low-cost reconfigurable end-user antennas that could be integrated with low-earth-orbit satellites so regional and remote Australians can access broadband. While broadband is taking its place alongside water and electricity as essential infrastructure, people in regional Australia lack genuine broadband services. These antennas are expected to give these communities reliable access to e-health services and distance education, and make their businesses more productive with access to new markets. The proposed antennas should also make broadband services available in the air, at sea, or on the move.Read moreRead less
