Invisible threads one step closer to reality

25 August 2010
Prof. Simon Fleming, Dr Boris Kuhlmey, Alessandro Tuniz and Dr Maryanne Large

IPOS student Alessandro Tuniz is working on a concept to make 1-micrometre invisible threads. His concept work combines techniques used to produce light-bending metamaterials with those used to make optical fibres to try and create real invisible threads. Alessandro Tuniz is interested in the optical metamaterials that are being formed into “invisibility cloaks” in labs across the world.

Alessandro is working to create invisible material by shrinking metamaterials to a small enough size to make them disappear in certain light wavelengths. His theory is based on “refractive index”, which measures the speed at which light travels through a substance. Physicists are able to shrink fibres to nanoscale using a process called fibre drawing. For invisibility the fibres need to be small before the tiny wavelengths of light travelling through them can be controlled. IPOS researchers Prof. Simon Fleming, Dr Boris Kuhlmey and Dr Maryanne Large, have produced threads that are 10 micrometre-thick threads.

Alessandro Tuniz has used computer modeling to design the invisible 1 micron thread. The project models calculations suggest that the thread would be invisible if seen from the side - rather than end on - in polarised light. The model shows that, like other optical metamaterials, the fibre's optical properties depend strongly on wavelength.

The county can’t face the technological future through copper wire

16 August 2010

An article written by Professors Ben Eggleton and David Moss, from CUDOS University of Sydney, has been featured in the Sydney Morning Herald.

Those who think our country can do without the national broadband network clearly do not fully understand the potential such a network offers to Australians. While other countries scramble to find ways to meet this exploding demand for global bandwidth, the opposition is wringing its hands and debating the need.

The network will do three things for Australia: it will pay for itself, it will stimulate the innovation economy and it will have multiple applications.

How do we know this? Because we are the scientists who are working right now to create the photonic and optical systems that will be installed in your home for the next 50 years. And we can assure Australians that all new systems in the future will depend on an optical fibre network to function.

We need to understand that the network will not just be an improved version of the present telecommunications network. It will be a fundamentally different and better system of doing business and connecting with each other and the world.

Other countries understand this and are scrambling to find the best way of implementing such networks of their own. Of the developed nations, only Australia remains stuck in the hand-wringing stage of debating whether such a system is even necessary.

Physicist Professor Ross McPhedran Honoured

8 June 2010
Prof. Ross McPhedran receives Honour

Professor Ross McPhedran, a senior researcher with IPOS, has been awarded a Doctorate Honoris Causa by The Universite Paul Cezanne. His award was presented during a ceremony in Aix en Provence, France, on June 7.

Professor McPhedran has been actively collaborating with researchers from this Universite, and its sister institution, the Universite de Provence, since 1973.

He is being acknowledged for his work on diffraction gratings, photonic crystals and microstructured optical fibres. In the last area, a highly successful new method was developed between Sydney and Marseille for the calculation of the optical properties of this new class of fibre.

Professor McPhedran said, "I am thrilled to be the recipient of such a prestigious acknowledgement. When I arrived in France, I was a green neophyte from Tasmania, with a good knowledge of irregular verbs and virtually no knowledge of spoken French."

"I learned a lot in my first year as a post-doctoral fellow in Marseille. This learning experience has continued over the years, with emerging young researchers as well as my colleagues of 1973. In the Centre of Excellence, CUDOS, in which I work, there is a strong group of Francophones and Francophiles."

There is a long history of research collaboration between Australia and France, dating back to the encounter between Nicolas Baudin and Matthew Flinders in 1802. Professor McPhedran is proud to be carrying on this fine tradition.

New laser to speed up information superhighway

2 June 2010
A/Prof David Moss

Associate Professor David Moss, a senior researcher at IPOS, leads an international team which has developed a new pulsed laser that allows light to be generated on a computer chip.

A/Prof Moss said the on-chip pulsed light source is the key to enabling ultra high speed signal processing and transmission of data either on-chip or between chips. Using light for ultrahigh speed information processing and transmission on a silicon chip is an important breakthrough. The ever-growing demand for even faster technology means ultrafast on-chip and chip-to-chip optical data communications are important.

The new laser produces short light pulses at record speeds to process and transmit information which can ultimately provide consumers with faster and cheap computers.

The New Inventors on ABC Television featured IPOS members David Hsiao-chuan and Prof. Simon Fleming

10 February 2010
IPOS scientist on ABC's The New Inventors

The Dental Laser Ultrasound developed by David Hsiao-chuan Wang and Prof. Simon Fleming, appeared on The New Inventors in ABC Television. The Dental Laser Ultrasound uses sound waves to detect faults in your teeth at an early stage eliminating the need for surgical intervention. The sound wave is generated by a laser and picked up by a thin optical fibre.

The Dental Laser uses an Ultrasonic Evaluation Technique using laser-generated ultrasound to measure the elasticity of the surface of teeth. Wang's painless technique uses a short laser pulse to generate ultrasonic surface acoustic wave on the surface of the tooth enamel. This ultrasound pulse propagates across the area of interest on the enamel, while probing some distance under the surface, and is detected for analysis. The calculated propagation velocity of the ultrasound then reveals the elasticity of the tooth, from which the early stages of decay can be diagnosed.

David Hsiao-chuan Wang is a PhD Research Student at IPOS, University of Sydney.

Prof. Simon Fleming is the Deputy Director and Business Development at IPOS, University of Sydney.
