Summary
Scientists have developed a number of incredibly powerful and sophisticated techniques to identify chemicals and measure their concentrations in the laboratory. However, it remains a major challenge to perform these measurements under everyday circumstances. For example, surface-enhanced Raman scattering (SERS) has gained widespread recognition as a technique for trace chemical detection, but it remains confined to a small number of specialist laboratories. For this reason, Dr Paul Stoddart at S ....Scientists have developed a number of incredibly powerful and sophisticated techniques to identify chemicals and measure their concentrations in the laboratory. However, it remains a major challenge to perform these measurements under everyday circumstances. For example, surface-enhanced Raman scattering (SERS) has gained widespread recognition as a technique for trace chemical detection, but it remains confined to a small number of specialist laboratories. For this reason, Dr Paul Stoddart at Swinburne University of Technology recognised a need for more practical SERS probes for field applications. His team has now developed a proprietary SERS probe, based on an optical fibre that is little thicker than a hair. These optical fibres can form the core element of field-portable SERS spectrometers. This work has recently been boosted by the discovery in the United States that SERS can be used to monitor glucose in blood. The development of a continuous glucose monitor has long been a holy grail of sensor research, because of the millions of diabetes sufferers who regularly perform the painful finger prick test. For SERS to provide a practical solution to glucose monitoring, it is recognised that SERS optical fibres are needed for minimally invasive probes. With support from Biopharmica and the Diabetes Australia Research Trust, Dr Stoddart's team has now demonstrated that sensitive SERS probes can be produced in large quantities. The next objective is to develop a prototype low-cost SERS spectrometer for use as part of a continuous glucose monitoring system. This will require the development of a laser source and spectroscopic system that can interface to the SERS probes. It is proposed to use an Australian designed and manufactured laser system based on a low-power narrow-linewidth laser diode. The project plans to bring together Swinburne University, OptoTech and Grey Innovation in order to develop a commercially scaleable and robust device.Read moreRead less

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.
Parallel Lines: Ultra-dense optical systems for extreme data-rates. The project aims to explore methods to significantly expand global internet data rates, by using emerging ultra-dense optical technologies. The project plans to discover how novel existing and emerging tiny photonic chip devices may enable the use of new, unused optical spectral bands, and then enable 1000s of channels to be supported by exploiting newly available parallelism in both wavelength and space.

The project aims to explore methods to significantly expand global internet data rates, by using emerging ultra-dense optical technologies. The project plans to discover how novel existing and emerging tiny photonic chip devices may enable the use of new, unused optical spectral bands, and then enable 1000s of channels to be supported by exploiting newly available parallelism in both wavelength and space. Success in the project aims may enable speeds of up to 100 times greater than achievable today, in a variety of fibre optic systems. Connectivity is key to our society, so benefits may arise in both future-proofing key Australian data infrastructure, and in providing a roadmap to support exponential capacity growth over the coming decades.Read moreRead less

Human-to-machine haptic communication allow humans to immersively interact with remotely-located robots/machines. Current networks cannot support its technical demands, thereby limiting the achievable human-machine distance. This project aims to develop cloudlet intelligence together with a programmable resilient network to realise reliable remote environment emulation, a concept where the physical environment at the remote machine is emulated close to the human. A key outcome will be the first reliable remote environment emulation platform that achieves vast human-machine distances on current networks. Enabling immersive human-machine experience will significantly benefit many sectors, from education through to industrial manufacturing.Read moreRead less

This project aims to address the need for new technologies to tackle the bandwidth overload. Because of the basic human desire to communicate and interact, our society has an exponentially growing Internet data demand. The data capacity crunch is imminent. Data demand is rapidly approaching the nonlinear Shannon limit which governs the maximum data capacity of single-mode optical fibres. Bandwidth limitations may have severe implications for society and economy. This project aims to develop chip-scale mode-multiplexers based on innovative 3D integrated photonics and combine them with optical gain to shape light for space-division multiplexed optical communication networks. This is designed to break through the data capacity limit that currently prevents growth in Internet data rates.Read moreRead less
