Advanced Microwave Facility for Quantum-Atom Optics. Atoms can be controlled using light in visible and infra-red regions, as well as electromagnetic waves of longer wavelength in the microwave (MW) and radiofrequency (RF) part of the spectrum. We presently use optical radiation to control atoms at the quantum level where they can behave like waves and can interact with light to store and manipulate information.

We presently use optical radiation to control atoms at the quantum level where they can behave like waves and can interact with light to store and manipulate information. The MW and RF facility will extend our abilities and enable more complete control of the atoms, which will help us develop the first generation quantum technology. This will enable the creation of quantum devices such as atom lasers, atom interferometers and quantum information networks for communication and ultra-sensitive measurement applications.Read moreRead less
Laser threshold sensing. This project aims to create a new class of room-temperature ultra-sensitive magnetometers based on laser threshold magnetometry. By using nitrogen-vacancy colour centres in diamond, these magnetometers will demonstrate at least femto-Tesla per root Hertz sensitivity, and could replace SQUID magnetometers.

The aim of this project is the application of new high spatial resolution techniques for determining the physical properties of such fibres. These methods will permit unprecedented knowledge of the precise distribution of rare-earth ions in the fibre and its relationship with the fibre's refractive index profile. This information is critical to understanding the performance of rare-earth-doped fibres in a variety of applications and the outcomes of this work will inform the design of fibres optimised for use in specific applications.Read moreRead less

This project aims to develop a new generation of bright, laser-like x-ray sources for laboratory use. X-ray sources underpin key diagnostic techniques in materials science, advancing applications from structural engineering through to ore processing and energy storage. However, the limited brightness of present-day laboratory x-ray sources restricts the utility and range of these diagnostic techniques. This research intends to use intense lasers to create microscopic plasmas and drive high harmonic generation. The high harmonic generation process is already used to create laser-like ultraviolet light. By optimising the characteristics of the plasma medium, the project aims to extend bright high harmonic generation to the x-ray regime.Read moreRead less
Fabrication of complete photonic band gap structures by two-photon polymerization and subsequent infiltration with high refractive index materials. The ability to shrink photonic circuits by orders of magnitudes by the integration of photonic crystals offers many stimulating possibilities for novel device designs. A speculative view is that this miniaturisation can have a similar impact to that experienced in electronic components in the 1960s.

The ability to shrink photonic circuits by orders of magnitudes by the integration of photonic crystals offers many stimulating possibilities for novel device designs. A speculative view is that this miniaturisation can have a similar impact to that experienced in electronic components in the 1960s. However, the fabrication of 3D photonic crystals remains a major challenge and the development of new, flexible, and fast nano-fabrication techniques is vital. The realization of an innovative technique for the fabrication of 3D complete photonic band gap structures as it is suggested will make an essential contribution to the emerging field of all-optical tele- and data-communications and will deliver major economic benefit to Australia.
