Optical fibre devices for sideways delivery of laser light during keyhole surgery. Mulitmode optical fibres are typically used to deliver high power laser light which is emitted from the end of the fibre to irradiate tissue during surgery. For intravenous delivery of laser light in the treatment of cardiac fibrillation (heart flutter) we require a sideways-directed illuminating beam. However reliable methods of delivering high power laser light in a sideways-directed beam are not currently avai ....Optical fibre devices for sideways delivery of laser light during keyhole surgery. Mulitmode optical fibres are typically used to deliver high power laser light which is emitted from the end of the fibre to irradiate tissue during surgery. For intravenous delivery of laser light in the treatment of cardiac fibrillation (heart flutter) we require a sideways-directed illuminating beam. However reliable methods of delivering high power laser light in a sideways-directed beam are not currently available. Using the ultraviolet laser fibre processing expertise already developed at Macquarie University, we propose to develop and characterise novel fibre-based devices which would allow controllable delivery of light sideways.Read moreRead less
Optical Fibre Touch Sensor for Cochlear Implants. The touch sensor will be part of a cochlear implant, which is surgically implanted to provide a sense of hearing for people who are profoundly or severely deaf. Approximately 100,000 people worldwide have received cochlear implants so far. However, the delicate internal structures of the ear can easily be damaged when the implant is inserted. By helping surgeons to preserve the inner ear, this sensor will help to further improve the hearing abili ....Optical Fibre Touch Sensor for Cochlear Implants. The touch sensor will be part of a cochlear implant, which is surgically implanted to provide a sense of hearing for people who are profoundly or severely deaf. Approximately 100,000 people worldwide have received cochlear implants so far. However, the delicate internal structures of the ear can easily be damaged when the implant is inserted. By helping surgeons to preserve the inner ear, this sensor will help to further improve the hearing ability of future patients. The 'bionic ear' was invented in Australia and this project will help to ensure the continued success of Australia's world leading implant industry.Read moreRead less
Untangling Complex Molecular Spectra with an Optical Frequency Comb. The exhaled breath is a rich source of information about the inner life of the human body - but untangling this complicated molecular mixture into a quantitative measurement of its constituent components is currently an unsolved problem. This project aims to develop a new instrument that leverages the Nobel Prize winning technology of the optical frequency comb to enable analysis of such mixtures. It is expected that by combini ....Untangling Complex Molecular Spectra with an Optical Frequency Comb. The exhaled breath is a rich source of information about the inner life of the human body - but untangling this complicated molecular mixture into a quantitative measurement of its constituent components is currently an unsolved problem. This project aims to develop a new instrument that leverages the Nobel Prize winning technology of the optical frequency comb to enable analysis of such mixtures. It is expected that by combining a frequency comb source, with an innovative detector and a highly sensitive sampling system, a real-time spectral signature of each sample will be generated. Computational techniques developed by the radio astronomy community will then be used to extract concentrations of individual molecular components at the parts-per-billion level.Read moreRead less
Optomechanical refrigeration of electronic circuits. The project aims to apply laser light to reduce the temperature of electronic circuits.

The project aims to apply laser light to reduce the temperature of electronic circuits. This aims to greatly suppress electronic noise, and enable a new class of technologies for future telecommunication systems. By developing new techniques to confine light, electric fields and vibrations at sub-micron scale on a silicon chip, devices such as ultralow noise amplifiers, clocks and radio frequency receivers will be realised, along with ultra-efficient optical modulators. In future, these technologies could reduce energy consumption and improve reliability in telecommunication networks. They could improve the range of satellite communication, robustness of GPS against cosmic radiation, and performance of surveillance systems such as radar and sonar.Read moreRead less
Nanophotonic metamaterials as anti-counterfeit devices in Australian banknotes. This project will demonstrate the application of novel materials as the basis for next generation security features on banknotes. Such elements play a key role in maintaining the integrity of Australia's currency since they present a significant barrier to counterfeiting.
