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

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
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. However, the fabrication of 3D photonic crystals re ....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. 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.

Ultra-stable photonic-chip pulse source. An ultra-low noise high repetition photonic-chip pulse source is proposed. This ultra-stable device offers orders-of-magnitude improvements over existing solutions and holds potential for strong improvements to analogue-to-digital converters. The laser will be a crucial component for photonic integrated circuits, enabling millimetre size processing.
Silicon Photonic Platform for Quantum Encryption and Communications. The integrity of a secure communications link can mean the difference between life and death in a defence environment. In the civilian arena, the security of electronic financial transactions is also critical to guard against 'cyber' theft. Encryption of data using unique quantum 'noise' as a key has been proposed as an exceptionally strong approach. Attempts to intercept the key during transmission can easily be detected.

Encryption of data using unique quantum 'noise' as a key has been proposed as an exceptionally strong approach. Attempts to intercept the key during transmission can easily be detected.
Quantum key transmission has been demonstrated but requires impractically expensive, bulky and exotic equipment. This project will explore low-cost, silicon chip based quantum key transfer modules. Our aim is to render quantum encryption as simple as adding an expansion card to a standard computer or portable device.Read moreRead less

This will enable the Internet to transfer vast amounts of data with significantly improved energy efficiency; it will lead to secure transmission using quantum photonics-based devices, and to the detection of mid-infrared signatures of light from distant stars and complex molecules of environmental or biochemical importance. We will achieve this by developing new materials with optical properties to control light and engineering them into miniature photonic processors.Read moreRead less
