These technologies are being applied to create new optoelectronic devices which could enhance optical communications or greatly reduce the cost of solar energy.
The £55 million building, currently under construction and due for completion in July 2008 will provide a world class facility that will allow ECS and the ORC to make more contributions in these exciting areas of research.
The fractals, which form an ornamental design on the glass of the new building, are inspired by research into optical metamaterials, conducted by Dr Darren Bagnall and Dr Adrian Potts at the University's School of Electronics & Computer Science (ECS) working with Professor Nikolay Zheludev of the ORC.
‘By drawing features that are much smaller than the wavelength of light, photons can be confused into doing things they normally wouldn’t do,’ said Dr Bagnall. ‘The chiral fractal structures when etched into glass at the nanoscale were shown to produce very unusual polarisation changes. By using similar technologies to produce other types of nanostructured arrays on the surfaces of solar cells we could also ensure that optical asymmetries are created that prevent light from escaping the solar cells.’
According to Dr Bagnall the light-trapping technologies could reduce the thickness of expensive semiconductor materials needed in solar panels, and this could directly reduce the cost of the devices. The first challenge is to prove that the technology works in practice, the second key challenge will be to develop cost effective ways to produce nanopatterned layers.
The research will continue in the new Mountbatten Building. The state-of-the-art, interdisciplinary facility designed specifically to meet the long-term research needs of the School of Electronics & Computer Science and the Optoelectronics Research Centre, contains a large purpose-built clean room and associated laboratories, along with offices and meeting space.
'The technology which will be available in our new building, coupled with our high-quality academics, students and support staff, will enable us to develop faster, smaller, lower-cost, lower power, more environmentally-friendly devices for the next generations of electronic products whilst continuing our pioneering work in computer science,' said Professor Harvey Rutt, Head of ECS.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
