Australia remains a world leader in enabling technologies spanning information and communication, lasers, photonic sensing and diagnostics and much more. Underpinning much of this have been key backbone facilities at UNSW and at Sydney. Optical fibre research internationally is moving in new directions and for Australia to continue its leadership role, dedicated facilities for new generation structured optical fibres, which are already impacting much more significantly than conventional fibres, must be available. The upgrade at UNSW will position Australia to continue its leadership and introduce educational and vocational training for the new industries that will depend on these core technologies.

This project aims to study new topologies for photonics-based interference mitigation filters for radioastronomy. Its significance is that it will solve, for the first time, the problem of excising RF interfering signals from within the optical signal fibre transport systems conveying radioastronomy signals from phased array antennas. These interference suppressors are key elements in removing strong unwanted man-made signals from terrestrial transmitters and satellites that coexist, and make the detection of the very weak radioastronomy signals extremely difficult. The outcome will be new high-resolution and tunable fibre-based interference suppression filters integrable with the signal transport system, which enhance the sensitivity of radioastronomy phased arrays.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.

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
