Shaping light – new frontiers in big fast data. This project aims to address the need for new technologies to tackle the bandwidth overload. Because of the basic human desire to communicate and interact, our society has an exponentially growing Internet data demand. The data capacity crunch is imminent.

This project aims to address the need for new technologies to tackle the bandwidth overload. Because of the basic human desire to communicate and interact, our society has an exponentially growing Internet data demand. The data capacity crunch is imminent. Data demand is rapidly approaching the nonlinear Shannon limit which governs the maximum data capacity of single-mode optical fibres. Bandwidth limitations may have severe implications for society and economy. This project aims to develop chip-scale mode-multiplexers based on innovative 3D integrated photonics and combine them with optical gain to shape light for space-division multiplexed optical communication networks. This is designed to break through the data capacity limit that currently prevents growth in Internet data rates.Read moreRead less

Summary
A femtosecond Mmd-IR optical parametric amplifier source for waveguide nonlinear optics. The mid-infrared is an immensely important region of the optical spectrum for sensing toxic or illicit molecules or pollutants using their spectral fingerprints.

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
