The project aims to apply laser light to reduce the temperature of electronic circuits. This aims to greatly suppress electronic noise, and enable a new class of technologies for future telecommunication systems. 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

On-chip generation and processing of high-power multi-GHz frequency combs. The project aims to deliver a chip-scale stable optical frequency comb technology with high-power and multi-GHz frequency spacing. The lack of this technology has prevented fundamental advances in wide-ranging applications that require high signal-to-noise-ratio (SNR) combs.

The project aims to deliver a chip-scale stable optical frequency comb technology with high-power and multi-GHz frequency spacing. The lack of this technology has prevented fundamental advances in wide-ranging applications that require high signal-to-noise-ratio (SNR) combs. The project seeks to demonstrate combs using waveguide laser technology and to integrate it with a reconfigurable optical filter to select and process individual comb lines. Key advantages of this technology, including high SNR, reconfigurability, high stability, small footprint and low-cost, are expected to improve astronomy’s ability to detect Earth-like planets, telecommunications to increase the overall internet capacity, and global positioning systems (GPS).Read moreRead less
Ultra-fast serialised all optical image processing: addressing the electronic bottleneck in the world's fastest camera. Serial time encoded amplified microscopy can capture over a million frames per second. At this rate, a megapixel image would fill a terabyte hard disk in a second. We will use photonics to condense and manipulated the video stream so that only the important features are 'seen', making it practical to process and store on a computer.

This project will focus on a goal of engineering novel plasmonic metamaterials for manipulating light at the nanoscale. In particular, it will employ curved anodized alumina templates as well as 3D hybrid structures to explore light bending and strong resonances at the visible spectral range. Plasmonic metamaterials offer a unique ability to control subwavelength light propagation, for achieving unprecedented sensing sensitivities and emerging nanophotonics phenomena. However, fabrication challenges and high losses hamper their application in the visible spectral range. Engineering these plasmonic structures in a scalable manner should strengthen Australia’s economy, lead to new industrial companies in the emerging field of plasmonics, attract international investments and create job opportunities.Read moreRead less
