This project aims to create multi-colour, ultrashort, highly coherent, bright pulses of soft X-rays based on high-harmonic generation in a table-top multiple-section gas cell. Studying multi-electronic and non-adiabatic processes and other fundamental aspects such as multi-electronic correlations and non-Born-Oppenheimer vibronic couplings in complex molecules is a major challenge in current ultrafast photochemistry research. This project will use multiple driving pulses with different carrier frequencies to control the spectral properties and time delay of the pulses. It will use the soft X-ray source to develop an ideal platform for studying multi-electronic and non-adiabatic processes, multi-electronic correlations and non-Born-Oppenheimer vibronic couplings in complex molecules. This is expected to advance materials science, paving the way to soft X-ray technologies.Read moreRead less

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
