Bifurcations of dissipative solitons. Fundamental research on the basic concepts of solitons in dissipative systems and their bifurcations is the next essential step for further progress in the science of optical pulse generators and amplifiers. Australia was the first country in the world to use self-organized ultra-short pulses, called solitons, in a commercially-deployed optical transmission line.

Australia was the first country in the world to use self-organized ultra-short pulses, called solitons, in a commercially-deployed optical transmission line. This proposed new research will answer the question of how solitons behave at the ultimate limits of optics. New principles of ultra-short pulse generation and amplification, developed in our research, will provide the basis for an unprecedented increase in the capacity of optical transmission and processing of information.Read moreRead less
Dissipative soliton resonances and their applications. Many branches of science and technology, such as precise eye surgery, biological cell machinery, painless dentistry, optical data storage, material micro-machining and laser fusion, rely heavily on high power femtosecond pulse laser oscillators that deliver the necessary power, in a very short time, to nanometer scale targets within a tissue or a material. A further increase in the power of a pulse and a decrease in its duration, combined wi ....Dissipative soliton resonances and their applications. Many branches of science and technology, such as precise eye surgery, biological cell machinery, painless dentistry, optical data storage, material micro-machining and laser fusion, rely heavily on high power femtosecond pulse laser oscillators that deliver the necessary power, in a very short time, to nanometer scale targets within a tissue or a material. A further increase in the power of a pulse and a decrease in its duration, combined with a reduction in complexity and price can be achieved, but this advance depends strongly on the theory of dissipative solitons, and particularly on the idea of soliton resonances. Novel ideas developed within this project will put new productive tools in the hands of doctors, biologists and physicists.Read moreRead less

Summary
Biofilms in two-dimensional turbulent flows:effects on Lagrangian transport. This project aims to investigate how surface biofilms affect flows at the ocean surface. Great stretches of the ocean surface are covered by an organic microlayer called biofilm. Flows at the ocean surface are a crucial part of climate machinery, and biofilms have profound, largely unexplored effects on these flows. There is no fundamental understanding of how biofilms affect fluid motion. This project aims to use labor ....Biofilms in two-dimensional turbulent flows:effects on Lagrangian transport. This project aims to investigate how surface biofilms affect flows at the ocean surface. Great stretches of the ocean surface are covered by an organic microlayer called biofilm. Flows at the ocean surface are a crucial part of climate machinery, and biofilms have profound, largely unexplored effects on these flows. There is no fundamental understanding of how biofilms affect fluid motion. This project aims to use laboratory models and new measurement techniques to study and quantify the impact of biofilms on turbulent transport. Understanding these effects is important in a time of climate change and this knowledge may also help address environmental issues related to spreading of pollutants and flow control at the ocean surface.Read moreRead less

Photonic crystals have recently became very attractive for photonic technology, that uses light instead of slow electrons as the information carriers replacing electronics in communications and information management. This project has the purpose to develop the fundamental concept of nonlinear photonic crystals and demonstrate their possible applications analysing the properties of the nonlinearity-induced light localization, nonlinear transmission, and frequency conversion in band-gap materials with the intensity-dependent optical response. This will allow the possibility realising in practice nonlinear switching even for sharply bent waveguides, providing an effective way to control the flow of light in band-gap photonic circuits.Read moreRead less
Plasmonic nano-antennas for next-generation photon sources. Extending concepts from standard radio-frequency antenna technology down to the nanoscale will open up new applications in fields from biotechnology to telecommunications. This project will embed a light emitting particle in a nanostructured metallic device to produce an ultrabright, directional single-photon source.
Solitons and localised structures in nonlocal nonlinear media. Solitons - localised waves existing in nonlinear media may propagate without changing their shape and interact with each other as real particles. They are ubiquitous in nature - exist in any system exhibiting dispersion and nonlinearity.

It will lay out theoretical foundations of the nonlocal solitons and d ....Solitons and localised structures in nonlocal nonlinear media.

The acoustics of a wide-range autonomous oscillator: how do brass players do it? While brass instruments are well understood, the complexities of the interaction with the player are not. This study will analyse how the player's lips and vocal tract interact with the instrument, leading to an understanding not only of the interesting physics involved, but to insight that will benefit players, teachers and students.

Materials science and engineering is decidedly interdisciplinary, covering a diverse spectrum of research from biology to construction, with an equally broad applications span encompassing all manufacturing industry. Australia has distinct strengths in materials but it has been difficult to promote sufficient interaction across discipline boundaries to fully exploit such strengths. The current network focuses on interdisciplinary materials interactions nationally by: i) bringing the materials community together at an annual workshop, ii) exposing PhD students and young researchers to cross-disciplinary research initiatives and facilities, iii) identifying common infrastructure needs, iv) linking with industry networks, eg AMTN, and to the international community.Read moreRead less
