This project aims to create a novel class of hybrid optical fibres that open new vistas for magnetic field detection at ambient temperatures in noisy environments. The multidisciplinary project will develop the first fibre laser threshold magnetometry platform that breaks through diamond magnetometry sensitivity limits by cross-cutting established fibre laser technology with the new diamond-glass fibres and magnetometry concepts recently invented by the investigators. Envisaged significant benefits include non-invasive detection of magnetic fields in hard-to-access regions, an area of key interest for remote detection of submarines, early sensing of aircraft corrosion, deep brain imaging of neuronal activities and mineral exploration.Read moreRead less

Conducting coatings for control and eradication of unwanted marine biofilms. Biofilms grow on all surfaces and environments posing environmental threats and economic issues globally, costing billions each year to those attempting to eradicate them. To date, biofilm's detailed response to variations in electrochemically generated redox stress and shear is unknown in marine environments.

Biofilms grow on all surfaces and environments posing environmental threats and economic issues globally, costing billions each year to those attempting to eradicate them. To date, biofilm's detailed response to variations in electrochemically generated redox stress and shear is unknown in marine environments. The project aims at (i) developing novel electrically conducting carbon based paints that are stable in marine environments and (ii) investigating how marine biofilms respond to these coatings. The expected outcome of this project is the development of a green alternative antifouling technology that can be used on demand in marine applications. This provides a new solution for controlling the biofouling of surfaces immersed in oceans.Read moreRead less

This project aims to investigate the growth and demonstration of compound semiconductor microring lasers on silicon substrates, using selective area growth to engineer the shape of the lasing cavity at the nano/micro-scale. Silicon photonics is currently a dominant technology in optical and data communication systems, and the continued development demands higher speeds, lower power consumption and lower costs. However, on-chip integrated, high efficiency lasers are still elusive due to mismatch in material platforms between the lasers and silicon substrates. This project will produce reliable, efficient and easily manufacturable laser sources integrated on silicon photonic chips. It is also expected to pave the way for more development of this technology by the industry to further drive the cost of silicon photonics technology down whilst increasing data transmission speed.Read moreRead less
