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

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. 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.

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
