This will require a different and more complicated theoretical approach to that which worked for optical lasers, but the result will be a device with a spectral flux which is orders of magnitude better than the current state of the art.Read moreRead less
Storage of non-classical light in a solid. A new scheme for storing and recalling coherent light pulses based on 'slow light' has been demonstrated. The aim of this project is to show how this can best be achieved in a solid to enable practical applications. A range of materials will be investigated. The novel feature of the storage is the maintenace of the coherence information and a noise analysis will be made to determine whether it is experimentally possible to store non-classical light.
Probing the Universe with gravitational waves: from cutting-edge technology to astronomy.

Across the Gravitational Wave Spectrum. Violent astrophysical events in the universe emit gravitational waves across a spectrum from mHz to kHz, producing an infinitesimal?but detectable'strain in space-time itself. Like high energy physics projects, gravitational wave detection involves giant multi million dollar research facilities and extensive international collaboration. This project will develop ideas, equipment and algorithms which will enhance the performance of both high frequency (gro ....Across the Gravitational Wave Spectrum.

Like high energy physics projects, gravitational wave detection involves giant multi million dollar research facilities and extensive international collaboration. This project will develop ideas, equipment and algorithms which will enhance the performance of both high frequency (ground) and low frequency (space) based laser interferometer type detectors, and see Australia expand its already important role in searching for nature's most elusive signals.Read moreRead less
Short-pulse laser cleaning for Australian heritage conservation. Conserving heritage objects is a demanding discipline, requiring a suite of techniques for different problems. Overseas, laser cleaning using long pulse techniques leaves microscopic damage as discrete chunks of material are removed, and is unsuitable for many materials. We have developed a short pulse laser process which can remove material molecule-by-molecule in a controlled fashion, and which can be readily halted once the fi ....Short-pulse laser cleaning for Australian heritage conservation. Conserving heritage objects is a demanding discipline, requiring a suite of techniques for different problems. Overseas, laser cleaning using long pulse techniques leaves microscopic damage as discrete chunks of material are removed, and is unsuitable for many materials. We have developed a short pulse laser process which can remove material molecule-by-molecule in a controlled fashion, and which can be readily halted once the final finish is achieved. We will research this technique for application to unique Australian heritage materials that are important to the specific conservation needs of the Australian War Memorial, the RAAF, Navy and Army Museums, Artlab Australia, and the Art Gallery of NSW.Read moreRead less

Quantum information and communication is a new paradigm in information technology which utilises quantum physics to improve current limitations in speed, security and fidelity of information transmission and processing, extending the present Electronics and Photonics devices. Future applications will include teleportation, cryptography and ultimately quantum computation. We propose to investigate these applications using continuous (CW) laser beams and the Einstein-Podolsky-Rosen (EPR) quantum entanglement, which is generated via a pair of optical parametric oscillators. The advantage of CW over the established single photon technology is better detection efficiency, wider data bandwidth and a compatibility with existing photonics technology.Read moreRead less

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
