Empowering optical metamaterials with gain. Artificial materials composites (metamaterials) make it possible for us to observe extra-ordinary properties, such as magnetic behaviour in glass and bending light in any direction. The project proposes to enhance the usability of metamaterials by redesigning them to strengthen their interaction with light, thus making them suitable for industrial applications.

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

This project aims to develop a new defect-control approach for silicon-germanium heteroepitaxial semiconductor systems to provide a route for high-throughput, low-cost, high-efficiency silicon tandem solar cells. Mismatched heteroepitaxy of semiconductors is of considerable interest for fabricating novel devices. However, the use of highly-mismatched heteroepitaxial semiconductors has been limited due to the high densities of crystal defects which degrade the performance of both majority and minority carrier devices. This project aims to develop a new defect-control approach for heteroepitaxial semiconductors by continuous wavelength diode laser processing. With heteroepitaxial silicon-germanium as an example, the project will investigate the mechanism underlying defect-cleaning, optimised designs for best performance, and designs for high-efficiency tandem solar cells.Read moreRead less

The project aims to develop next-generation organic-inorganic halide solar cells which are stable and non-toxic. Although rapid progress has been made in the emerging perovskite solar cell technology, it currently relies on lead as a key perovskite component. The elimination of lead from organic-inorganic halide perovskite solar cells would greatly increase their acceptance as an alternative thin film photovoltaic solution because of their low cost and non-toxic nature. The dearth of lead-free perovskite solar cell demonstrations and the relatively low conversion efficiencies demonstrated understate their potential. This project plans to improve understanding of their photovoltaic enabling attributes by characterising and modelling their optical and electrical properties. It then plans to apply new fabrication methods to develop lead-free solar devices.Read moreRead less
