The Fano resonance in plasmonic nanostructures and metamaterials

Nat Mater. 2010 Sep;9(9):707-15. doi: 10.1038/nmat2810. Epub 2010 Aug 23.


Since its discovery, the asymmetric Fano resonance has been a characteristic feature of interacting quantum systems. The shape of this resonance is distinctively different from that of conventional symmetric resonance curves. Recently, the Fano resonance has been found in plasmonic nanoparticles, photonic crystals, and electromagnetic metamaterials. The steep dispersion of the Fano resonance profile promises applications in sensors, lasing, switching, and nonlinear and slow-light devices.
