LATEST NEWS 2012

2012 National ERA rankings are out - The University of Sydney scores highest in the fields iPL contributes to  - optical physics 5/5, macromolecular and materials chemistry 5/5, materials engineering 5/5, communications technologies 5/5, nanotechnology 4/5 (5/5 well above world standard, 4/5 above world standard). 

Note that these ERA rankings do not cover all areas and therefore have no measure of other key fields iPL contributes to such as sensing and related topics.

November 2012
Former student Roberson Oliveira who spent 2010 doing his PhD in our group has received special commendation from CAPES the Brazilian funding agency for his oustanding thesis work, much of it carried out in Australia. His thesis was entitled: "Characterization and new applications of the acouto-optic effect in fibre Bragg gratings".
Roberson also won the 2010 3rd Asia Pacific Optical Sensors (APOS) conference Best Student Award for work which was published in Sensors and Actuators B: Chemical.
He can be seen lurking at the back with other team members standing in this group posing at the open-air construction site of the Guangzhou Communications Tower in China 400 meters high before its completion. In the background the city of Guangzhou is visible.

September 2012: Inorganic self-assembly work accepted to Nature Communications

The work pioneered at iPL where novel silica optical microwires are fabricated by convective self-assembly and fracturing has been accepted to Nature Communications. It also describes a new room temperature approach to complex material fabrication based on intermolecular forces, enabling almost any material composite to be envisaged.  This method offers a solution to the one of the truly great material challenges of our time: overcoming the differences in energy and thermal processing between disparate media such as silica and organics to create new hybrid materials with complex properties. The key high temperature processing barrier of silica was resolved and both organic dyes and nanodimaonds were integrated. It provides an excellent template for topology based assembly, new theoretical directions for designing entirely new structures which are also an ideal analogue for studying molecular self-assembly, both at a microscopic level but also in terms of the net role of intermolecular forces in long range assembly and collective interactions. The new technique has potential for a range of applications not only in photonics but more generally, including electronic, photovoltaic, sensing, biodiagnostics and more. We welcome collaborations to pursue any aspect both at a fundamental and an applied level - contact. Prof. Canning. Stay tuned for the work to come out - a preliminary piece was deposited in aRxiv Feb this year.

September 2012: D-shaped fibres from the new National Fibre Facilty at UNSW

Collaborative work between The University of Sydney and Aarhus University has seen visiting PhD student Lars Glavind, supported by Vestas Denmark, one of the world's leading windmill manufacturers having recently been commissioned to install over a billion dollars of windmill infrastructure in Australia, has successfully fabricated with colleagues at the University of NSW, D-shaped fibre for sensing applications. A range of specialty long period and Bragg gratings were inscribed into the fibre.

The D-shape fibre follows the successful fabrication of record breaking Bi-doped optical fibre earlier in the year - work which results in several publications for UNSW including a breakthrough in signal transmission by NEC in the United States using the fibre as a few mode amplifier demonstrating the feasibility of few mode communications to increase capacity. A key paper detailing some of the relevant properties of the fibre was recently published with iPL in Optics Letters. See the 2012 publication list for more details.

September 18 2012: Bulk regeneration accepted to Applied Optics. 

Visiting Endeavour Fellow Dr. Liyang Shao has had our work on bulk regeneration accepted for publication in Applied Optics. It demonstrates the feasibility of practical regeneration for eventual commercial production of ultra high temperature grating sensors.  Sources for variation and the origin of wavelength shifts are identified.
For those interested in commercial opportunities in developing this tehcnology please contact Prof. Canning. Prof. Canning will be at OFS in Beijing and will be presenting a talk on the latest in regeneration at the symposium Advances and Trends in Fibre Optics and Applications (ATFO), in Wuxi, China.

June 22 2012: Advances in Engineering reports on our work mapping temperature profiles inside MCVD preforms More . Research published in the Int. Journal of Heat and Mass transfer see publications 2012 where we detail how we use an array of four regenerated gratings for the first time. The temperature is mapped along and across the preform tube under typical fibre fabrication conditions. Until this work the temperature mapping was only numerical and started with an assumption that there was no significant temperature gradient across the tube wall from the outside in. Our results indicate under typical conditions this is unlikely and that a significant drop up to 700 °C or more exists. Removing the assumption and simulations appear consistent with experiment, warning in part the dangers of relying on simulations for accurate profiling. For optical fibre fabrication, understanding accurately the temperature profile is critical to understanding thermal gradients and currents and therefore thermophoretic effects, which in turn effects the subsequent deposition and volatility of dopants and their reaction chemistry, for example.

March 2012: Special Issue of Springer Open Photonic Sensors: The best of photonic sensor research down under.

Call for papers: APOS 2012 revealed major photonic sensing research across Australia and its disproportionate impact both in the region and globally. In recognition of this impressive array of work, Photonic Sensors journal has called for a special issue highlighting the best of Australian research at APOS 2012. In addition. Guest Editors, Prof. Gang-Ding Peng and Prof. John Canning.

 


February 2012: Does fibre optic sensing technology have the failsafe potential to both enhance oil and gas recovery and improve environmental monitoring to better ensure safe and responsible production? Oil and Gas Technology reports on our work through a recently concluded Department of Innovation, Industry Science and Research (DIISR) funded project and the work of others in looking towards enhancing the properties of photonic technologies for applications in harsh and indeed extreme sensing environments. The work involves collaboration with Prof. Cicero Martelli and colleagues in Brazil as well as with colleagues from the Institute of Photonics, Jena Germany. More

Feb 5, 2012: Important delegation from University of Electronic Science and Technology (UESTC), Chengdu, China and elsewhere visit the University of Sydney

UESTC is one of the top technology institutions in China, modeled on MIT, with the top ranked undergraduate programs in engineering and expanding into basic sciences. The delegation visited both UNSW (led by Prof. Gang-Ding Peng) and USyd (led by Prof. John Canning) faculties of Science and Engineering. The visit paves the way for major bilateral relations between Australia and China, expanding both educational and research ties. The foundations for ideal China-Australia funding programs in photonics, sensing and wireless were laid and the basis for significant other interactions across China and Australia were explored.

Feb 3, 2012: Friday evening formal reception launch of the new national fibre facility at UNSW

With a gathering of some of the world's most illustrious and important expertise in optical sensing, both from abroad and from overseas, the new national fibre facillity was launched at the Scientia Building at UNSW. A challenging tour given the numbers involved, saw a quick trip through major photonic facilities at UNSW, including the quantum research centre, before culminating with the icing on the cake - the southern hemisphere's tallest draw tower, custom designed from years of experience leading advanced fibre fabrication both at the former Optical Fibre Technology Centre and at UNSW for application specific optical research fibre. A relaxed barbeque-style reception and drinksunderscored the importance for good relations and good cooperation both locally and globally.
