New grants put UK photonics group on stronger wavelength

14.03.2007
Three grants totalling more than one million Euros have been awarded to Aston University in Birmingham, UK, to help revolutionise the use of fibre optic cables in engineering, medicine and telecommunications.

In one of the projects, experts at Aston's Photonics Research Group will use ultraviolet laser radiation to create sensing devices known as fibre Bragg gratings inside plastic optical fibres, enabling the fibres to be used to accurately measure temperature inside the human body or determine stresses and strains in aircraft wings and also bridges.

The major goal of the second project is development of new fabrication technology for waveguide-microchip lasers. Fabrication of a compact and robust laser with monolithic cavity based on crystals doped with rare-earth or transition metal ions is the target of the project. The developed technology will promote miniaturization of solid state lasers and will facilitate their integration in electronic systems.

The third project targets prototype all-optical regeneration solutions related both to optical fibre networks and optical interconnects.

The awards have been given through an EU funded competition within the Sixth Framework Human Resources and Mobility Programme, known as the Marie Curie Actions. The Photonics Research Group has been awarded two Marie Curie Incoming International Fellowships, hosted by Dr. D.J. Webb and Prof. I. Bennion; and one Marie Curie Chair hosted by Prof. S.K. Turitsyn. Under the grants experts Dr A Okhrimchuk of the Russian Academy of Science, Dr H Liu of the University of New South Wales in Sydney and Prof. V Grigoryan from Northwestern University, USA will join the Photonics Research Group to help perfect new optical technologies.

Fibre Bragg gratings are created by using laser radiation to write micron-sized structures inside an optical fibre - a 'light pipe' that traps photons in a small core, which is ten times smaller than a human hair. The grating then reflects light of only one wavelength back down the fibre, the precise wavelength depending on how much the fibre is strained or heated. The use of polymer as opposed to glass cables makes this process more flexible, extensive - it takes three times more strain than glass - and safer, as for instance the polymer cannot shatter inside the human body.

The first gratings in the new style fibres have been produced, attracting invitations for the research group to present keynote talks in Hong Kong, Brazil and France. The Photonics Research Group works with such companies as BAE, Airbus, France Telecom and Ericsson and also the Department of Trade and Industry.

"These three grants are a strong indication that there is something very special about the work we are doing here," said Prof. Sergei Turitsyn of the Photonics Research Group. "The fact that so many people want to work with us means we are fast becoming a centre of excellence in this field," he added.

His colleague Dr David Webb said: "The competition for the Marie Curie Actions is Europe-wide and the success rate of applications less than 20 percent, so it is clear the experts making the awards recognised the high standard of the environment and people here in the research group."

The internationally renowned Photonics Research Group, the second largest of its kind in the country, was formed in 1991 and has around 50 staff involved in research and development of applications-orientated telecommunications, sensors, fibre grating technology, nonlinear optics and bio-photonics.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
