The development of communications is vital to Australia's future. Our project will enable both massive improvements of the performance of the communication technologies and significant reductions in the cost and size of the associated infrastructures. The resulting benefits will contribute to developing the economy and lifestyle of rural and regional Australia. The expansion of a faster network throughout the country will eventually enable advanced techniques and services such as remote surgery, remote engineering and distance education. We will provide advanced training for three students who will gain valuable skills in this area that will be sought after by the Australian information and communication technology industry.

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
