Stimulating light scattering in periodic structures: How slow can it go? Proof-of-concept experiments have already proven that it is possible to reduce and control the speed of light within the laboratory. This fundamental change in our understanding of light properties generated a frenzy of scientific interest and we now have a basic understanding of the physical processes involved in slowing light.

Proof-of-concept experiments have already proven that it is possible to reduce and control the speed of light within the laboratory. This fundamental change in our understanding of light properties generated a frenzy of scientific interest and we now have a basic understanding of the physical processes involved in slowing light. What we do not have, however, is a method of doing so that can be harnessed into useful applications outside of the lab. Our proposed approach offers a low power solution that can be readily incorporated into a myriad of engineered devices.Read moreRead less

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

This project aims to make the fluoride glass fibre platform the preferred material for generating ultrashort pulses at 2.8 nm and beyond. High power and efficiency from simple device architectures are essential for industry, medicine and defence. Modern sources of short pulses of light emitting mid-infrared wavelengths are complicated and inefficient. This project will improve fibre sources emitting short pulses and create the essential building blocks for future all-fibre arrangements that will be more robust. The sources are expected to have applications in non-linear optics and materials modification.Read moreRead less
Unlocking the ultraviolet. This project will develop a new class of ultra-short-pulse and broadly tunable laser with performance in the ultraviolet that is unobtainable from current infrared-based laser technologies. Our invention will unlock the elusive ultraviolet part of the spectrum to allow new discoveries in fundamental science and to drive twenty-first-century technologies.
A versatile optical wavelength and mode switching device for future telecommunication networks. This project will develop a next generation switching device for future fibre optical communication networks that will divide their information among several modes of specialty fibre. This device will be a key component for allowing network operators to move to these novel mode-multiplexed networks in order to overcome the looming capacity crunch.

This project aims to apply Brillouin processing to the development of an innovative, self-tracking optical filter for isolating optical carriers in the coherent receiver of future ultrahigh bit-rate optical communication systems. By recovering a needle-like optical carrier with great precision from a drifting sea of wide-band noise and data channels, the project expects to minimise the effect of optical carrier distortions on the data-carrying signals. The project should advance knowledge in optical signal processing and communications technologies, with outcomes that increase the data-carrying capacity of optical networks. Future telecommunication networks should benefit through improved transmission rates and extended fibre links.Read moreRead less
Broadband compensation of nonlinear signal distortion in optical fibre communications. This project will investigate novel optical technologies for overcoming the approaching data capacity limits of global optical communication networks that are caused by transmission errors from nonlinear signal distortion in optical fibre. The research will show that light propagation through specially designed waveguides can cancel the distortion.
