Picosecond optical probing and characterization of infrared and visible devices. The facility consists of a laser to generate short infrared pulses, and an oscilloscope and detectors to measure such pulses. It will be used to characterize and investigate a new generation of novel optical fibre devices and microstructures, which are to form the basis of the next generation of telecommunications systems, and also novel and unique laser types.

It will be used to characterize and investigate a new generation of novel optical fibre devices and microstructures, which are to form the basis of the next generation of telecommunications systems, and also novel and unique laser types. The research and development of all of these devices are receiving external funding (or are in negotiations therefore). The facility allows for high-speed and high-accuracy data acquisition, which makes it unique in Australia.Read moreRead less
Novel multi-channel and nonlinear Bragg grating devices. High capacity and reliable telecommunications links are essential for many aspects of modern life and work. Optical fibres offer essentially unlimited capacity, but their optimal use requires the transmission of multiple wavelength channels simultaneously. This, in turn, requires the development of special-purpose fibre devices for multiplexing and de-multiplexing these channels, as well as for other optical filtering and switching tasks. ....Novel multi-channel and nonlinear Bragg grating devices.

This, in turn, requires the development of special-purpose fibre devices for multiplexing and de-multiplexing these channels, as well as for other optical filtering and switching tasks. Fibre Bragg gratings are central to many of these devices, and the aim of this project is to develop novel designs for linear and nonlinear Bragg grating devices which may significantly widen the current range of their applications.Read moreRead less

Light-matter interactions in microstructured optical waveguides for nonlinear optical signal processing. The challenge of conceiving and constructing the necessary components and devices for the next generation of lightwave telecommunications systems is a profound one.

This issue is urgent as the current operating principles of switches, filters and sources and other devices simply do not allow for the upgrade to the extremely high data transmission speeds that will be required. Using glass optical fibres as the starting point, we will devise, demonstrate and analyze these novel components, leveraging microstructured optical fibre technology and novel fabrication techniques, which are among the most recent developments in optical fibre research.

The development of communications is vital to Australia's future. Our project will enable both massive improvements of the performance of the communication technologies and significant reductions in the cost and size of the associated infrastructures. The resulting benefits will contribute to developing the economy and lifestyle of rural and regional Australia. The expansion of a faster network throughout the country will eventually enable advanced techniques and services such as remote surgery, remote engineering and distance education. We will provide advanced training for three students who will gain valuable skills in this area that will be sought after by the Australian information and communication technology industry.

Optical parametric amplifiers with exceptional qualities using highly nonlinear optical fibre. Current optical fibre networks use only a fraction of their capacity. This is in part because optical amplifiers with enough bandwidth do not exist. However, it will soon become necessary to exploit all of this capacity.

However, it will soon become necessary to exploit all of this capacity. This project will create a new highly nonlinear optical fibre with very low loss and tailored dispersion properties. This will then be used to make an optical fibre parametric amplifier with a world record bandwidth, which will enable the full capacity of optical fibre to be exploited.Read moreRead less
