Optical-OFDM provides Australia with an opportunity to develop a new, high-tech, easy-to-export technology with a very large market potential spanning three key communications markets: wireless personal-area networks, local-area networks and long-haul (80-4000 km) optical networks. It is based on innovative Australian technology generated from two research strengths: photonics and OFDM. OFDM is already the basis of most non-optical broadband systems, including digital broadcasting and ADSL. Patent applications have been filed. One application enables bandwidths to rural and remote communities to be quadrupled without laying new cables. By launching off this local market Australian industry can develop a world leading industry.Read moreRead less

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 aims to investigate the design of a broadband ?photonic antenna? for airborne radar warning and electronic countermeasure systems. The project will investigate the development of a suite of printed antennas that cover bands in the range from 2-40 GHz realised on a single substrate.
