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. Data demand is rapidly approaching the nonlinear Shannon limit which governs the maximum data capacity of single-mode optical fibres.

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

Improved fibre Bragg grating sensors for detection of structural hot spots. Structural integrity monitoring, to anticipate and prevent failure, is a multi-billion dollar effort worldwide. Detailed assessment of the capability of fibre Bragg gratings to measure strain profiles along the grating length, i.e. intragrating sensing, and thereby detect structural ?hot spots? before failure is essential for effective systems.

Structural integrity monitoring, to anticipate and prevent failure, is a multi-billion dollar effort worldwide. Detailed assessment of the capability of fibre Bragg gratings to measure strain profiles along the grating length, i.e. intragrating sensing, and thereby detect structural ?hot spots? before failure is essential for effective systems. They will be used to determine strain gradients similar to those found in common problem areas, such as the tips of elliptic notches and disbonding at the ends of composite joints. Additionally, grating refractive index profiles will be characterised using imaging techniques, to assess performance and possible changes to gratings after prolonged use.Read moreRead less

By developing new techniques to confine light, electric fields and vibrations at sub-micron scale on a silicon chip, devices such as ultralow noise amplifiers, clocks and radio frequency receivers will be realised, along with ultra-efficient optical modulators. In future, these technologies could reduce energy consumption and improve reliability in telecommunication networks. They could improve the range of satellite communication, robustness of GPS against cosmic radiation, and performance of surveillance systems such as radar and sonar.Read moreRead less
