Microwave-modulated optical systems for free-space and undersea communications. Although offering flexible, rapid deployment, free space and underwater comunications have not kept up with progress in optical fibre communications, and current systems are signficantly restricted in range and data rate. To address these needs, we will develop novel laser systems using coherent detection, with infrared output for eyesafe transmission in air, and blue-green output for transmission underwater. The s ....Microwave-modulated optical systems for free-space and undersea communications. Although offering flexible, rapid deployment, free space and underwater comunications have not kept up with progress in optical fibre communications, and current systems are signficantly restricted in range and data rate. To address these needs, we will develop novel laser systems using coherent detection, with infrared output for eyesafe transmission in air, and blue-green output for transmission underwater. The signal is a microwave modulation on the optical carrier, which permits longer-range transmission while maintaining signal coherence. Key advantages include increased detection sensitivity, and potential to scale up the modulation frequency and the power for higher data rates and longer propagation distance.Read moreRead less

Removing the blur: Guidestar lasers for the space industry . The speed and quality of transferring information between earth and space can be greatly enhanced by adaptive optical systems that provide correction for atmospheric aberrations. The laser-generated guidestars that lie at the heart of these systems must be bright, preferably multi-coloured and with low background.

The speed and quality of transferring information between earth and space can be greatly enhanced by adaptive optical systems that provide correction for atmospheric aberrations. The laser-generated guidestars that lie at the heart of these systems must be bright, preferably multi-coloured and with low background. By taking advantage of the unique optical properties of diamond, this project aims to develop lasers that produce these advanced features to fulfil the needs of the space industry sector. These outcomes are expected to create new services and products in the areas of space situational awareness, space debris management and satellite communications, and have major spin-off benefits to astronomy and defence.Read moreRead less

The project aims to establish a state-of-the-art facility to conduct optics and photonics experiments at ultra-low temperatures, by integrating an optical-access cryogen-free dilution refrigerator into an optics laboratory. Near absolute zero temperature, complex materials and engineered nanoscale devices exhibit striking quantum mechanical behaviour. Experimental access to photonics at millikelvin temperatures would enable a coherent quantum-mechanical interface between spins, charges, phonons and photons. This unique facility may help in designing the next generation of information, communication and metrology devices, such as quantum computers, single-photon sources and detectors, and nanoscale quantum-enhanced sensors.Read moreRead less
Stimulating light scattering in periodic structures: How slow can it go? Proof-of-concept experiments have already proven that it is possible to reduce and control the speed of light within the laboratory.

Proof-of-concept experiments have already proven that it is possible to reduce and control the speed of light within the laboratory. This fundamental change in our understanding of light properties generated a frenzy of scientific interest and we now have a basic understanding of the physical processes involved in slowing light. What we do not have, however, is a method of doing so that can be harnessed into useful applications outside of the lab. Our proposed approach offers a low power solution that can be readily incorporated into a myriad of engineered devices.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
