A well known example is the giant magnetoresistance, a phenomena discovered over fifteen years ago that now plays a key role in current high density magnetic disc drives. Future developments will involve spin dependent transport through structures wherein quantum interference effects will be important. Two basic problems facing the construction of a complete theory of transport in such ?mesoscopic? conductors will be solved in this project. The results will provide important insights into the dynamics of spin transport through structures such as magnetic nano-wires.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
Collision data for lighting industry and plasma modeling. The project's primary aim is to progress the design of more efficient
and environmentally friendly light sources. Given the number of light
sources in use worldwide even a small improvement in the efficiency
could lead to enormous benefits to society via reduction of energy
consumption. Design of new mercury-free light sources will eliminate a
major neuro-toxin pollution source. Collaboration with research groups

Modelling and Measurement of Flow-Structure Dynamics in the Human Upper Airway. Sleep disruption due to the common and disabling conditions of snoring and obstruction of the human upper airway can result in chronic fatigue, lost work and accidents caused by daytime drowsiness. To date the behaviour of the upper airway has not been adequately studied in terms able to reveal the mechanical causes of these conditions. This deficiency is addressed through the development and use of simulation tools ....Modelling and Measurement of Flow-Structure Dynamics in the Human Upper Airway. Sleep disruption due to the common and disabling conditions of snoring and obstruction of the human upper airway can result in chronic fatigue, lost work and accidents caused by daytime drowsiness. To date the behaviour of the upper airway has not been adequately studied in terms able to reveal the mechanical causes of these conditions. This deficiency is addressed through the development and use of simulation tools and measurement techniques that will elucidate the flow-structure dynamics leading to new diagnostic and improved treatment methods. Simulating the effect of treatment on any individual will permit it to be chosen to maximise its efficacy for a problem that costs the nation an estimated $2 Billion per year in lost productivity.Read moreRead less
