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.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
