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

This project addresses two critically important technologies needed to meet these demands: signal processing devices and antennas. These devices will be designed using three-dimensional photonic crystals, which provide excellent possibilities for low-cost, highly integrated photonic circuits. Working prototypes will be built at microwave frequencies, but due to the scalability of electromagnetic theory these results are also valid in the optical domain. The outcomes of this project will be accurate theoretical models and empirical tests for new technologies that satisfy the future needs of the information society.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
