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.

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

Summary
A Transportable Optical Frequency Counter, Synthesizer and Super-Continuum Generator (OFCSSG). The generation of ultra-short light pulses of just a few femtoseconds (one thousand-trillionth of a second) in duration has enabled applications in a wide range of fields, but complexity and cost has limited availability.

The generation of ultra-short light pulses of just a few femtoseconds (one thousand-trillionth of a second) in duration has enabled applications in a wide range of fields, but complexity and cost has limited availability. This project will employ recently developed optical fibre and solid-state laser technology to create a cost-effective compact transportable facility of highly coherent, ultra-broadband radiation. The source will enable new research and substantially enrich existing research in optical time standards and metrology, in-vivo biological imaging, and ultrafast spectroscopy. No such facility is presently available in AustraliaRead moreRead less

The project aims to improve the accuracy of automatic location identification of GPS enabled handsets in third-generation cellular networks via a modified Differential GPS method. The proposed sub-metre location ability will be a value-added service of the network providers and will appeal to a wide sector of users. The challenge is to develop a cost effective solution by utilising existing network infrastructure. We propose to use the GPS timing units in 3G networks for deriving local GPS position corrections; and to transfer these corrections to the users via the 3G data bursts of the beacons or other user data broadcasts.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
