Summary
Advances in nanotechnology have led to new techniques for the precise fabrication of nanometre scale structures. A recent breakthrough by the applicants now allows high-quality nanostructures to be stamped onto the tip of low-cost optical fibre probes. When coated with silver, these sensitive probes can be used for continuous monitoring of blood glucose in diabetics and in critical care situations. This project aims to develop a prototype manufacturing system for optical fibre glucose probes.
Dual wavelength quantum dot light detectors. This project aims to develop technologies to fabricate advanced electronic materials based on gallium antimonide (GaSb), to explore their physics and use them in improved optoelectronic devices.

This project aims to develop technologies to fabricate advanced electronic materials based on gallium antimonide (GaSb), to explore their physics and use them in improved optoelectronic devices.
GaSb technology is in its infancy, therefore basic and applied research is needed to utilise these materials to their full potential for long wavelength photonic devices with unique promise in military and civilian applications: fire detection, missile and surveillance systems, environmental monitoring, biology and medicine.
As an outcome, growth protocols for innovative device structures will be established, the structures' behaviour assessed and device fabrication and characterisation carried out and reported.

Summary
The commonest beating disorder of the heart is atrial fibrillation (AF). Whilst it can occur at any age it is more common in the elderly with 12% Australians over 70 y.o having it. AF is the cause of a third of all strokes and increases the risk of dying from any heart disease. Ventricular tachycardia (VT) is the commonest cause of death in the year after a heart attack. Currently these beating disorders are in most cases incurable and respond poorly to medications. We have developed an operatio ....The commonest beating disorder of the heart is atrial fibrillation (AF). Whilst it can occur at any age it is more common in the elderly with 12% Australians over 70 y.o having it. AF is the cause of a third of all strokes and increases the risk of dying from any heart disease. Ventricular tachycardia (VT) is the commonest cause of death in the year after a heart attack. Currently these beating disorders are in most cases incurable and respond poorly to medications. We have developed an operation for AF which is done by open heart surgery. It has been successful at curing some patients who suffer from AF and uses radiofrequency energy. The difficulty of radiofrequency energy is that it is not suitable in a large number of cases for this operation. We are developing Laser and Microwave catheters as alternatives to RF so that the success of the operation can be improved. These new microwave and laser catheters are being designed and tested to be used primarily in a minimally invasive procedure. They would be inserted via the veins with the patient under sedation. This would allow patients to go home sooner and have a recovery period of only a few days. As well as their application in the top chamber of the heart (atrium) for AF, these new energies will be adapted for minimally invasive operations in the ventricle (lower chamber) of the heart for the treatment of ventricular tachycardia. By developing a technique such as this, cure of AFand VT will be available to many more people, helping reduce the strokes, heart failure and premature deaths from these two heart conditions.Read moreRead less
Digital Interferometry: A platform technology for robust optical measurements. Digital interferometry is a new concept which will allow the measurement precision of interferometry to be applied in otherwise inaccessible or unsuitable environments.

It will enhance the performance of major scientific instruments, such as gravitational wave detectors and optical telescopes, whilst reducing the cost, giving Australia a high profile in the quest to understand the universe. When applied to everyday situations, such as surveillance, traffic flow or vibration monitoring, it can give Australian industry a economic and social advantage, increasing the wealth and security of the nation.

Microprobing of Crystal Polarisation in Polycrystalline Compound Semiconductors. We will improve the quality of polycrystalline compound semiconductor thin films, grown by chemical vapour deposition. The novelty of the project is divided between applying new methods to assess film quality and deposition development. An expected outcome will be a measurement system with the unique capability of probing the spatial variation of dielectric polarisation with sub-micron resolution.

The novelty of the project is divided between applying new methods to assess film quality and deposition development. An expected outcome will be a measurement system with the unique capability of probing the spatial variation of dielectric polarisation with sub-micron resolution. Polycrystalline GaN recently been taken to state of the art performance at Macquarie University, will be the trial material. The information obtained will inform material improvement, with the ultimate aim of fabricating polycrystalline, GaN-based transistors and blue light-emitting diodes on glass substrates.Read moreRead less

Fundamental optics research underpins the commercial optical technologies of tomorrow. Modern examples of such evolution, from the fundamental to the commercial, include lasers, LED traffic lights, thin-screen computer monitors and digital cameras. The recent advent of accessible powerful computers, together with recent advances in optical physics, promise a powerful merging of computing and optical technologies into so-called virtual optical systems in which the computer processes optical information in a manner very similar to lenses. In particular, the computer may be used to decode distorted images provided by an imperfect imaging system. Read moreRead less
