Australian access to world leading technology in state-of-the-art infrared detectors is key to future advanced systems for defence surveillance and sensing, mineral exploration, biomedical instrumentation, precision agriculture, environmental monitoring and homeland security. This project will ensure that Australia contributes to an integral component required in the development of these technologies allowing early access to future systems. It will also enable Austarlia to play a leading role in setting the research directions for infrared materials that will place Australian research at the forefront in this area.Read moreRead less
Investigation of 1/f noise mechanisms in HgCdTe heterostructure IR photodiodes. Since the performance of any photon detector is defined by its signal to noise ratio, the reduction of noise generating mechanisms is equally important to improvement of the signal. In this project we propose to carry out, for the first time, a comprehensive analysis of noise generating mechanisms in HgCdTe detectors using recently developed, two-dimensional analysis procedure. The main objective of this project is t ....Investigation of 1/f noise mechanisms in HgCdTe heterostructure IR photodiodes. Since the performance of any photon detector is defined by its signal to noise ratio, the reduction of noise generating mechanisms is equally important to improvement of the signal. In this project we propose to carry out, for the first time, a comprehensive analysis of noise generating mechanisms in HgCdTe detectors using recently developed, two-dimensional analysis procedure. The main objective of this project is to prove that 1/f noise in HgCdTe photodetectors is caused by dark current fluctuations in the high electric field regions of the detector structure. The primary outcome of this work will be the first comprehensive two-dimensional device model that can predict 1/f noise in a semiconductor device.Read moreRead less

This research aims to study a new reconfigurable MicroPhotonic processor capable of performing many optical functions simultaneously. In this project, research is particularly focused on reconfigurable optical add/drop multiplexing (ROADM) for future Dense Wavelength Division Multiplexed (DWDM) optical networks. The significance of the MicroPhotonic architecture is that it can add/drop a single or multiple wavelength channels, and can scale to tens of channels while maintaining low insertion loss and low crosstalk. The outcome will be a new reconfigurable MicroPhotonic ROADM architecture which overcomes existing scaling bottlenecks for processing hundreds of DWDM channels.Read moreRead less
Quantum dynamics of solid-state qubits. The primary aim of this project is to carry out a critical assessment of several solid-state qubit systems and quantum logic gate operations through detailed theoretical calculations. This project will address important issues such as precise control of electron flux and spin interactions, optimal operating conditions, errors due to imperfection in the system and possible mechanisms for error elimination, as well as reliable measurements of the output qubi ....Quantum dynamics of solid-state qubits.

This project will address important issues such as precise control of electron flux and spin interactions, optimal operating conditions, errors due to imperfection in the system and possible mechanisms for error elimination, as well as reliable measurements of the output qubit register. In addition, qubit systems have shown themselves to be tiny laboratories in which fundamental concepts in quantum mechanics can be tested and a new regime of physics can be learnt.Read moreRead less

Excitation of spin-wave modes in confined in magnetic nano- and submicro-objects (from the super-paramagnetic size limit up to 700 nm) will be theoretically studied. In co-operation with other research groups the obtained theoretical results will be experimentally verified. New information on microwave properties of the structures will be obtained. Possibility of application of the magnetic structures to construct new microwave devices will be considered.Read moreRead less
