Summary
Nonlinear optical phononics: harnessing sound and light in nonlinear nanoscale circuits. This project will open a new field of physics by building the first integration platform in which light and sound interact in nonlinear nanoscale circuits.

Optical data storage is one of the core aspects of optical information technology which has been globally recognised as one of the next generation high-technology areas that can boost our economy for sustainable development. However, the emergence of blue ray or high-definition DVDs has identified that current optical data storage technology will soon approach the limit of the data storage capacity of approximately 100 Gigabytes. The ground-breaking Petabyte data storage technology we will research will result in the storage capacity of 10,000 DVDs in one disc and thus underpin every sector of our modern life such as remote education, portable banking, global e-security and telemedicine as well as lead to enormous economic benefits in Australia.Read moreRead less

The optical microscope has enabled us to see micro-objects, leading to revolutionary discoveries in medicine and natural sciences. However, the smallest object resolved by a microscope is limited by the wavelength of light. To see nanoscale objects smaller than the wavelength, a new tool for nano-imaging is needed. This project will establish a nanoscale optical microscopy facility that will reveal the topology and true colours of the nano-objects. Such information, achieved through spectroscopic analysis of the light emitted or scattered at the nanoscale, will uncover some of the most fundamental aspects of the nanoworld, leading to cutting-edge scientific discoveries and important industrial applications in photonics and solar energy.Read moreRead less
Hybrid plasmonic waveguide for integrated photonic signal processing. Fast processing of information is central to modern society. This task is traditionally carried out by electronics, which however is becoming too slow and energy-consuming for some tasks. Among alternative technologies optics is the most promising, because it is fast and potentially energy efficient, but possible optical solutions are either quite bulky or suffer from high ohmic losses because the light needs to travel through ....Hybrid plasmonic waveguide for integrated photonic signal processing. Fast processing of information is central to modern society. This task is traditionally carried out by electronics, which however is becoming too slow and energy-consuming for some tasks. Among alternative technologies optics is the most promising, because it is fast and potentially energy efficient, but possible optical solutions are either quite bulky or suffer from high ohmic losses because the light needs to travel through metal. This project aims to design and fabricate a device which emits a train of short pulses, a key requirement for any signal processing, and in which the light resides mostly in low-loss material. By using metals merely to confine the light, such a 'hybrid' device would avoid the drawbacks of traditional photonic solutions.Read moreRead less
