Fano Resonance to be Combined with Metamaterials and Plasmonic Nanostructures

Due to the breakthrough in the field of Fano Resonance, which in tandem with plasmonic nanostructures and metamaterials could be the beginning of a legion of new applications in sensors, slow devices, lasers and so on. The applications could be used for bioanalysis and chemical probes that may be suited for high-throughput systems, and also sensors which are electronic free, for sensing temperature or pressure.

Miniature nanoantennas used in wireless connections or in mobile telephones, optical waveguides, interferometers, displays etc. can be created using fano resonance. Pioneered in 1961 by Ugo Fano, it shows a marked asymmetrical line profile, allowing interference phenomena on nanoscales. Fano resonance’s unique sensitivity (especially in plasmonics) prodded scientists to explore its utility in diverse applications.

In the past for almost half a century, the spotlight with regard to fano resonance was in quantum systems, but currently it was discovered by a few independent scientific teams, that this resonance could be taken in by metamaterials and plasmonic substances. A*STAR (DSI) Data Storage Institute’s Professor Boris Lukiyanchuk, was the one of the foremost researchers to use fano resonance in these kind of materials, and the outcome of these studies along with other similar explorations from other groups in Rice University, U.S., University of Southampton, UK, Imperial College, London and University of Stuttgart, Germany, have been published in the form of a review paper, online, on the 23rd August 2010 in Nature Materials, According to Dr Pantelis Alexopoulos, DSI’s Executive Director, future possibilities include creating a new recording technology, if the sensitivity effect of fano resonance is integrated into a new recording media. DSI’s aim is to be a significant link in a knowledge centric global community mainly for nurturing R&D.
