By developing new techniques to confine light, electric fields and vibrations at sub-micron scale on a silicon chip, devices such as ultralow noise amplifiers, clocks and radio frequency receivers will be realised, along with ultra-efficient optical modulators. In future, these technologies could reduce energy consumption and improve reliability in telecommunication networks. They could improve the range of satellite communication, robustness of GPS against cosmic radiation, and performance of surveillance systems such as radar and sonar.Read moreRead less

This project aims to create devices to measure and manipulate the spatial and temporal properties of light. The ability to control or measure the spatial and/or temporal properties of light is a fundamental feature of many applications, including biomedical imaging, astronomy, telecommunications, high-power lasers and quantum computing. This project will develop five prototype systems to control the spatiotemporal properties of light in ways that were previously not possible. This would affect fundamental and applied applications where the inability to sufficiently control light’s spatial and/or temporal properties is an impediment. Examples include imaging deep into ‘opaque’ objects such as human skin or brain, high-power lasers for material processing and manufacturing, optical telecommunications and quantum computation.Read moreRead less
