SA Minister for Science visits CoEP facilities

August 6, 2009

This week the South Australian Minister for Science, the Honourable Micheal O’Brien MP, visited the University of Adelaide  and was given a short tour of the CoEP’s experimental facilities. These include state-of-the-art fibre and glass making facilities along with fibre characterisation labs.

Minister O’Brien was shown the glass and fibre fabrication approach and witnessed a live fibre draw – the process by which a macroscopic glass ‘preform’ is drawn down to a microscopic optical fibre.

We hope the Minister enjoyed his visit and would like to thank him again for taking the time to tour our facilities.

Exciting seminar by Phillip Russel

April 3, 2009

The CoEP is pleased to announce that it will be hosting a seminar on Thursday the 9th of April given by Prof Phillip Russel. This event is a free public lecture and all are welcome.

Prof Russell is considered a ‘godfather’ of microstructured optical fibre research worldwide, and is known for giving quite insightful talks.

Currently he serves as the Director of the newly founded Max-Planck Institute for the Science of Light and Professor of Physics at the University of Erlangen-Nuremberg, Germany.  He obtained his PhD (1979) degree at the University of Oxford and has subsequently held positions in France, Germany, the USA and the UK.  He specializes in the behaviour of light in periodically structured materials and waveguides, and was the founder of BlazePhotonics Ltd (2001 to 2004) whose aim was the exploitation of photonic crystal fibre. Prof Russell is a Fellow of the Royal Society and the Optical Society of America and has won several international awards for his research.

The details of the talk are are given below, followed by the abstract.

Location: Kerr Grant theatre, Physics building, University of Adelaide.

Time: 6pm

Glass cages for catching light

In its most common form, photonic crystal fibre (PCF) consists of a hair-thin thread of glass with a ‘cage’ of tiny hollow channels running along its length. This periodic lattice makes it possible to guide light in new ways, for example, to cage it inside an empty core. In such a hollow-core PCF one is able for the first time to eliminate the diffraction of light over km distances in empty space. By filling the core with gases, nonlinear gas-laser interactions can be enhanced by seven orders of magnitude in the best low-loss PCFs. Hollow-core PCF can also be used, for example, to laser-guide small particles, molecules or atoms along a curved path. In PCFs with micron-sized solid-glass cores, the chromatic dispersion can be radically altered, which has led to a revolution in the brightness of broad-band white-light sources. The most recent example of such  supercontinuum” sources is nearly six orders of magnitude brighter than an incandescent lamp, yielding up to 10 mW/nm spectral intensity at visible and near IR wavelengths. The lattice of hollow channels also gives rise to phononic band gaps and families of multi-GHz guided acoustic modes, which themselves interact strongly with light, creating unusual forward and backward Brillouin spectra. By filling the hollow channels with metals such as silver or gold, one can explore plasmon resonances in arrays of parallel nanowires. Through its unique and varied characteristics, PCF is creating many new opportunities in diverse areas of fundamental and applied research.
