Mullins-type effects in soft filled viscoelastic solids. Bread dough is made in vast quantities daily, and improvements in processing,especially sheet rolling,are needed,and to enable this we propose to create a novel mathematical description of the material. Also, wheat breeding cycles can be drastically shortened by using knowledge of dough rheology, since baking quality is closely linked to rheology.

Also, wheat breeding cycles can be drastically shortened by using knowledge of dough rheology, since baking quality is closely linked to rheology. The mathematical framework can then be applied to other filled viscoelastic systems, and work on liquid crystals may be used to develop artificial muscle material, once their rheological description and behaviour are known.Read moreRead less

New Pulsar Instrumentation for Gravitation Wave Detection and Understanding the Emission Mechanism. Millisecond pulsar timing currently provides the most sensitive method of detecting long-period gravitational waves which permeate the Universe. Parkes leads the world in the discovery and timing of millisecond pulsars. This has motivated the development of three new advanced instruments including a cyrogenic dual-band receiver, a very wide-band correlator and a baseband recorder with an in-built ....New Pulsar Instrumentation for Gravitation Wave Detection and Understanding the Emission Mechanism. Millisecond pulsar timing currently provides the most sensitive method of detecting long-period gravitational waves which permeate the Universe. Parkes leads the world in the discovery and timing of millisecond pulsars. This has motivated the development of three new advanced instruments including a cyrogenic dual-band receiver, a very wide-band correlator and a baseband recorder with an in-built supercomputer. We aim to exploit these new technologies to systematically study the pulsar population. We will establish a timing array which can detect gravitational waves, enable GLAST to identify over 100 gamma-ray pulsars and study the pulsar emission mechanism at sub-microsecond time resolution.

The information society in which we live requires increasingly high bandwidth, low cost communications. This project addresses two critically important technologies needed to meet these demands: signal processing devices and antennas. These devices will be designed using three-dimensional photonic crystals, which provide excellent possibilities for low-cost, highly integrated photonic circuits. Working prototypes will be built at microwave frequencies, but due to the scalability of electromagnetic theory these results are also valid in the optical domain. The outcomes of this project will be accurate theoretical models and empirical tests for new technologies that satisfy the future needs of the information society.Read moreRead less

Lithium niobate has the potential to become the silicon of the optoelectronic industry. In order to realise its potential, fundamental problems associated with long term stability and cost of integration need to be solved. This project will develop a new hybrid fabrication platform that circumvents the traditional approaches pursued in the past for introducing waveguides into a lithium niobate chip. This platform will enable the production of robust, low cost light sources for fields as diverse as biotechnology, environmental sensing and displays. This project will lead to new IP that will establish Australia as a leader in this field.Read moreRead less
Laser Micro-Fabrication of Optoelectronic Devices. The project aims to develop new techniques of laser direct-write fabrication of microstructures (1-100 micron in size) in crystalline materials, and to apply these to fabricating periodically-poled nonlinear crystals for optical frequency conversion. These techniques will use laser ablative surface profiling with subsequent electric field poling, and a completely new process of laser temperature profiling with simultaneous field poling, to writ ....Laser Micro-Fabrication of Optoelectronic Devices. The project aims to develop new techniques of laser direct-write fabrication of microstructures (1-100 micron in size) in crystalline materials, and to apply these to fabricating periodically-poled nonlinear crystals for optical frequency conversion. These techniques will use laser ablative surface profiling with subsequent electric field poling, and a completely new process of laser temperature profiling with simultaneous field poling, to write periodic domains in lithium niobate. Such laser direct-write processing is well suited to rapid prototyping and will enable investigation of novel periodically-poled structures, for example, chirped, fanned and multiplexed structures for nonlinear spectral and temporal conversion.Read moreRead less

By giving a global perspective of the field from its origins those outside the field will be able to appreciate its importance and its place in contemporary physics. Quantum gravity researchers will be able to see how their preferred approach fits into the web of research programmes, thus opening the door for greater collaboration between the various approaches. This research will greatly enhance Australia's position in this breakthrough science.Read moreRead less
Optical parametric amplifiers with exceptional qualities using highly nonlinear optical fibre. Current optical fibre networks use only a fraction of their capacity. This is in part because optical amplifiers with enough bandwidth do not exist. However, it will soon become necessary to exploit all of this capacity. This project will create a new highly nonlinear optical fibre with very low loss and tailored dispersion properties. This will then be used to make an optical fibre parametric ampli ....Optical parametric amplifiers with exceptional qualities using highly nonlinear optical fibre.

However, it will soon become necessary to exploit all of this capacity. This project will create a new highly nonlinear optical fibre with very low loss and tailored dispersion properties. This will then be used to make an optical fibre parametric amplifier with a world record bandwidth, which will enable the full capacity of optical fibre to be exploited.Read moreRead less
