Harnessing opto-acoustic interactions for on-chip optical isolation. The project aims to develop practical on-chip photonic isolators – one-way optical circuits – by harnessing light–sound interactions in a nanoscale platform novel in its materials, design and mechanism. The project should develop new nanofabrication techniques and transform understanding of the physics of one-way photonic processes.

The project aims to develop practical on-chip photonic isolators – one-way optical circuits – by harnessing light–sound interactions in a nanoscale platform novel in its materials, design and mechanism. The project should develop new nanofabrication techniques and transform understanding of the physics of one-way photonic processes. Expected outcomes include enhanced design and fabrication capabilities for photonic circuits, ultra-compact, high-performance optical isolators and circulators that shield sensitive optical components, and a suite of theoretical tools for describing propagation and noise in these devices. These new high performance photonic circuits should benefit telecommunications, radar, defence, and sensing applications. Read moreRead less
Catching the fast waves: high speed RF sensing using Brillouin scattering. This project aims to develop a room temperature approach to fast sensing of microwave electromagnetic waves by harnessing stimulated Brillouin Scattering (SBS), simultaneously achieving high frequency range, high resolution and high-speed performance. This project expects to generate new knowledge in microwave photonics and SBS, specifically elucidating the transient temporal response of SBS. Expected outcomes of this pro ....Catching the fast waves: high speed RF sensing using Brillouin scattering. This project aims to develop a room temperature approach to fast sensing of microwave electromagnetic waves by harnessing stimulated Brillouin Scattering (SBS), simultaneously achieving high frequency range, high resolution and high-speed performance. This project expects to generate new knowledge in microwave photonics and SBS, specifically elucidating the transient temporal response of SBS. Expected outcomes of this project include a proof of concept RF sensor that has multi-Gigahertz real-rime instantaneous bandwidth with high-resolution that can be miniaturized on to a chip. This compact RF sensor, will play a vital role for situational awareness in space, defence and communications applications. Read moreRead less
