The aims of this project are to develop detailed finite-difference time-domain numerical models of active photonic crystal structures, and to use them to optimise the design and performance of photonic-crystal-based devices, especially micro-cavity lasers. Photonic crystal microlasers have the potential to provide very efficient and low noise laser sources in micron-sized cavities, however the simplistic structures used to realise these lasers to date provide sub-optimal performance. Innovative designs with improved performance will be developed by tailoring both the optical and thermal properties of planar photonic crystal stuctures. Devices designed during this project will subsequently be fabricated at facilities in France.Read moreRead less

Modern materials scientists and engineers are driven by world-wide competition to develop new technology and manufactured devices. The trend has for some time been towards miniaturisation and one of the main challenges lies in effectively characterising nanostructures that are produced as a key step in research and development of advanced materials. The proposed electron microscope and detectors will provide a state-of-the-art analytical facility to support the cross-disciplinary materials science and nanotechnology research at the Australian National University. It will also provide an important training facility for students and early-career researchers and will be available to investigators from other Australian institutions.Read moreRead less
Power scaling of remote plasma sources for gallium nitride film growth with real-time monitoring of activated nitrogen species. Domestic, industrial and community lighting currently accounts for ~20% of the world's overall energy consumption. Commonly used incandescent lights are based on inefficient, century-old technologies. In contrast, light emitting diodes (LEDs) use ~80% less energy and last ~100 times longer. LED deployment will bring substantial economic and environmental benefits for Au ....Power scaling of remote plasma sources for gallium nitride film growth with real-time monitoring of activated nitrogen species. Domestic, industrial and community lighting currently accounts for ~20% of the world's overall energy consumption. Commonly used incandescent lights are based on inefficient, century-old technologies. In contrast, light emitting diodes (LEDs) use ~80% less energy and last ~100 times longer. LED deployment will bring substantial economic and environmental benefits for Australia and globally. Next generation high-efficiency LEDs for lighting, will operate with reduced energy consumption, thus contributing to reaching future national targets for CO2 emission reduction. This project will achieve reduced production cost of a key LED material, and will support Australia's leadership in a growing global semiconductor manufacturing industry.Read moreRead less
Optical Biomimetics of Diatoms. Optics is a research and economic strength of Australia. We will aim to provide a new optical sensor for chemicals using a diatom. This use of an optical device found in nature is groundbreaking and may provide a more efficient form of sensor to help to detect pollution such as metals in marine environments.

We are on the verge of an optical processing revolution. The silicon industry evolved from valves to transistors and finally to processors - Optical processing is the next step in the evolution of lasers from gas to solid state, and ultimately to integrated optical chips. Australia had a significant lead in semiconductors during the 1970?s, but unfortunately lost this lead due to a lack of local market. The emergence of biotechnology and telecommunications offer strong local markets for this new integrated optical technology. This project aims to create a world-leading Research capability in Australia to drive the evolution of integrated optoelectronics, and provide a commercial path to create a leading Australian industry.Read moreRead less
