With the exponential growth in global bandwidth demand, the speed, cost, size, and energy requirements of telecommunications equipment are reaching a crisis point. This project will pioneer ultra-high speed silicon integrated all-optical signal processing devices that will provide faster, cheaper and more energy efficient solutions than current electronic based approaches. In doing so, this will also directly benefit the Australian photonics, telecommunications, and defence industries. It will use novel structures such as nanowire waveguides and micro-ring resonators to demonstrate all-optical signal regeneration, wavelength conversion, demultiplexing and other functions at speeds up to 160Gb/s.Read moreRead less

Asymmetric InP-based structures for high power laser diodes at 1400-1500 nm for pumping optical amplifiers used in communication systems. This project is aimed at obtaining high power, single mode 1400-1500 nm wavelength laser diodes using a novel design of asymmetric InP-based structures. These devices are in great demand for pumping of erbium-doped and Raman amplifiers for powering the next generation of dense wavelength division multiplexing optical networks.

This project is aimed at obtaining high power, single mode 1400-1500 nm wavelength laser diodes using a novel design of asymmetric InP-based structures. These devices are in great demand for pumping of erbium-doped and Raman amplifiers for powering the next generation of dense wavelength division multiplexing optical networks. The low modal gain (confinement factor) of this asymmetric structure is expected to reduce internal losses and hence increase the output power with better thermal dissipation. Single mode could be obtained by careful design in the trade-off between filamentation and threshold current. Ion implantation is also proposed to suppress higher order modes.Read moreRead less

Modern materials scientists and engineers are driven by world-wide competition to develop new technology and manufactured devices. The trend has for some time been towards miniaturisation and one of the main challenges lies in effectively characterising nanostructures that are produced as a key step in research and development of advanced materials. The proposed electron microscope and detectors will provide a state-of-the-art analytical facility to support the cross-disciplinary materials science and nanotechnology research at the Australian National University. It will also provide an important training facility for students and early-career researchers and will be available to investigators from other Australian institutions.Read moreRead less
Nanoscale nonlinear optics. Advances in nanotechnology have led to the realisation of nanoscale photonic components that enable integration within electronic chips. Now the challenge is to make these components perform computing functions themselves, thus providing ultra-high operation speeds and reducing power consumption.

This project will utilize the intensity dependent interaction of light with metal-dielectric nanostructures to establish new processing functions of the photonic components. Our research underpins integration of photonics in future generations of computers and enables novel applications in subwavelength optical imaging and sensing. This project will therefore strongly enhance the standing of Australia in the field of nanotechnology.Read moreRead less

We are on the verge of an optical processing revolution. The silicon industry evolved from valves to transistors and finally to processors - Optical processing is the next step in the evolution of lasers from gas to solid state, and ultimately to integrated optical chips. Australia had a significant lead in semiconductors during the 1970?s, but unfortunately lost this lead due to a lack of local market. The emergence of biotechnology and telecommunications offer strong local markets for this new integrated optical technology. This project aims to create a world-leading Research capability in Australia to drive the evolution of integrated optoelectronics, and provide a commercial path to create a leading Australian industry.Read moreRead less
