Summary
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.

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.

Mechanical stresses in holey fibres. The development of holey fibres constitutes arguably the most exciting development in fibre optics in recent years. We will analyze the mechanical stresses in these fibres, which, together with the optical calculations and associated experiments, will allow us to design novel fibre-based devices. This will allow Nufern to develop new products based on holey fibres.

More sophisticated designs and combinations will allow arbitrary shaping of the optical field exiting an optical fibre for numerous applications. The physical basis for such phenomena to be realised is the efficient degree of coherent scattering possible in air-material fibre such as air-silica photonic crystal fibres. In conjunction advanced characterisation techniques will be developed.Read moreRead less

These will include novel grating-array based 2-D DFB lasers and filters in rare-earth doped planar waveguides. Novel etching techniques to be used to enhance index contrast, as well as to characterise such devices, will be developed based on our recent observation of hydrogen-enhanced etching of glass. Such methods could potentially be applicable to not only photonic technologies but also semiconductor lithography of oxides.Read moreRead less
