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.

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.

The exhaled breath is a rich source of information about the inner life of the human body - but untangling this complicated molecular mixture into a quantitative measurement of its constituent components is currently an unsolved problem. This project aims to develop a new instrument that leverages the Nobel Prize winning technology of the optical frequency comb to enable analysis of such mixtures. It is expected that by combining a frequency comb source, with an innovative detector and a highly sensitive sampling system, a real-time spectral signature of each sample will be generated. Computational techniques developed by the radio astronomy community will then be used to extract concentrations of individual molecular components at the parts-per-billion level.Read moreRead less
