A Laser Guide Star using a High Power, Synchronously Pumped Optical Parametric Oscillators. We will develop a novel high power source of 589nm coherent (laser) light to be used to create a laser guide star by exciting sodium atoms in the earth's upper atmosphere (the mesosphere). This is needed to determine the distortion caused by the atmosphere on an optical beam propagating through it and generate the information needed to correct those distortions using an adaptive optics telescope.

New error correction strategies for continuous variable quantum key distribution. Quantum key distribution is a completely secure method for two distant parties to share a unique secret key. The aim of this project is to design new algorithms, construction tools and analysis techniques to produce new iterative error correction codes, which will improve the operational distance and performance of quantum key distribution.
Application of Femtosecond Light Sources to Generation of Low Noise Microwave Signals. The main goal of the research project is to develop prototypes of photonic oscillators capable of generating spectrally pure signals both at optical and microwave frequencies. The project is also aimed at understanding noise mechanisms affecting frequency stability of classical microwave oscillators based on sapphire loaded cavity resonators. By cryogenically cooling such resonators we plan to create a new fam ....Application of Femtosecond Light Sources to Generation of Low Noise Microwave Signals. The main goal of the research project is to develop prototypes of photonic oscillators capable of generating spectrally pure signals both at optical and microwave frequencies. The project is also aimed at understanding noise mechanisms affecting frequency stability of classical microwave oscillators based on sapphire loaded cavity resonators. By cryogenically cooling such resonators we plan to create a new family of extremely low noise and economically viable microwave signal sources. The research proposed will enrich the field of oscillator frequency control, give rise to new techniques for precision noise measurements and reinforce Australia's position at the forefront of microwave and photonic science.Read moreRead less

Meeting the global demand for mobile and wireless communications depends critically on reliable and high rate data transfer. Unfortunately, communications medium idiosyncrasies pose formidable challenges. Very recently, in combatting this, major breakthroughs have been achieved whereby the use of multiple antennas allows for drastic data-rate increases. These advances use sophisticated Space-Time coding methods, and while they are causing great excitement in terms of their simulation performance, it is not clear how they will perform in practice, or in fact how they are to be realistically implemented. This project will address this issue by building a world-first testbed that implements a high rate wireless communications system using Space-Time and other coding methods.Read moreRead less
