Microstructured optical fibres have been defined as the 'next generation' of optical fibres. This proposal offers the opportunity to make major advances in this dynamic new area, not only changing the fibre properties by means of its microstructured but also by its material properties.

The aims of this project are to develop detailed finite-difference time-domain numerical models of active photonic crystal structures, and to use them to optimise the design and performance of photonic-crystal-based devices, especially micro-cavity lasers. Photonic crystal microlasers have the potential to provide very efficient and low noise laser sources in micron-sized cavities, however the simplistic structures used to realise these lasers to date provide sub-optimal performance. Innovative designs with improved performance will be developed by tailoring both the optical and thermal properties of planar photonic crystal stuctures. Devices designed during this project will subsequently be fabricated at facilities in France.Read moreRead less
Microwave-modulated optical systems for free-space and undersea communications. Although offering flexible, rapid deployment, free space and underwater comunications have not kept up with progress in optical fibre communications, and current systems are signficantly restricted in range and data rate. To address these needs, we will develop novel laser systems using coherent detection, with infrared output for eyesafe transmission in air, and blue-green output for transmission underwater. The s ....Microwave-modulated optical systems for free-space and undersea communications. Although offering flexible, rapid deployment, free space and underwater comunications have not kept up with progress in optical fibre communications, and current systems are signficantly restricted in range and data rate. To address these needs, we will develop novel laser systems using coherent detection, with infrared output for eyesafe transmission in air, and blue-green output for transmission underwater. The signal is a microwave modulation on the optical carrier, which permits longer-range transmission while maintaining signal coherence. Key advantages include increased detection sensitivity, and potential to scale up the modulation frequency and the power for higher data rates and longer propagation distance.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.
