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
Optical supercontinuum generation from high pulse-energy optical sources. The aim of this project is to develop a broadband and high brightness optical fibre source based on optical supercontinuum generation (i.e. low-coherence optical signals with octave or more bandwidth). Unlike similar sources demonstrated recently which rely on expensive bulk femtosecond pump lasers, this source will be pumped by a large pulse-energy optical fibre laser and use stimulated Raman scattering to seed the contin ....Optical supercontinuum generation from high pulse-energy optical sources. The aim of this project is to develop a broadband and high brightness optical fibre source based on optical supercontinuum generation (i.e. low-coherence optical signals with octave or more bandwidth). Unlike similar sources demonstrated recently which rely on expensive bulk femtosecond pump lasers, this source will be pumped by a large pulse-energy optical fibre laser and use stimulated Raman scattering to seed the continuum generation. The primary outcome will be a compact low-cost all-fibre supercontinuum source with a wide range of applications in areas such as optical metrology, optical coherence tomography, and high resolution non-contact position and motion sensing.Read moreRead less

Fighting terrorism and crime is one of the most important and difficult tasks that requires substantial human and technological resources. This project will help to address this enormous problem by developing a new optical sensor technology for the detection and identification of traces of chemicals, explosives, drugs and biological agents. It will develop a laboratory prototype of this sensor that is expected to have superior sensitivity and operational capabilities. Thus it will noticeably contribute to practical law enforcement, air quality and environmental monitoring, counter-terrorism, air safety, border security and customs service. It will also lead to further development of nano-optics and nanotechnology in Australia. Read moreRead less
