Subradiant, superradiant and Fano resonances in dimer and ring/disk nanocavities
… parent plasmons. We observe the appearance of Fano resonances in the optical response of plasmonic nanocavities due to the coherent coupling between their superradiant and subradiant plasmon modes due to structural symmetry breaking. Both subradiant modes and Fano resonances exhibit substantial …

Novel terahertz and nanophotonic lasers : theory, design, and fabrication
… experimentally the existence of special type of Fano resonances at k~~0 in a macroscopic two-dimensional photonic crystal slab. We fabricate a square lattice array of holes in silicon nitride layer and perform an angular resolved spectral analysis of the various Fano resonances. We elucidate …

Dynamic control of plasmonic resonances with graphene based nanostructures
… properties of graphene and plasmon resonances in metallic nanostructures to achieve dynamic control of plasmon resonances. First, we show that it is possible to use the highly tunable interband transitions in graphene to effectively control the plasmonic resonance in mid-infrared …

Green function studies of the interlayer exchange coupling in magnetic multilayers
… the coupling, in particular in the appearance of Fano resonances. Finally, we studied how the coupling changes when roughness, alloying of the spacer, or strain are present. In all cases, the results were in very good agreement with experiment, showing that the AGF method is a very accurate, and …

From fano to nano: mechanisms and applications of surface enhanced raman spectroscopy
… asymmetric peak shapes can result, known as Fano resonances. This may be useful in SERS: more energy confined to the region near the nanostructures and proximal analyte molecules, provides a larger SERS enhancement. In the literature, there appears to be an evasion of an experimental SERS …

Plasmon hybridization in real metals
… that the extinction spectrum exhibited a narrow Fano resonance. Using the plasmon hybridization approach and group theory we showed that this Fano resonance is caused by the interference of two bonding dipolar subradiant and superradiant plasmon modes of E1u symmetry. We investigate the effect of …

Complex Plasmonic Nanostructures: Symmetry Breaking and Coupled Systems
… band electrons called localized surface plasmon resonances. Plasmons couple efficiently to light and have enabled a new class of technology for the manipulation of light at the nanoscale. Nanostructures that support plasmon resonances have the potential for a wide range of applications such as …

Manipulation of Light-Matter Interaction in Two-Dimensional Systems via Localized Surface Plasmons
… to study the localized surface plasmon (LSP) resonances via reflection measurements and numerical simulations. Due to the grating created by arrays of bowties, a new, lattice-coupled LSP (lattice-LSP) mode emerged. Comparing the calculated E-field enhancement of the bowtie arrays to the …

Designing subwavelength-structured light sources
… the higher quality factor lasing mode (dark Fano resonance) is selected through the symmetry mismatch to the free-space modes. The PCSELs have not only achieved the highest surface-emitting single-mode power but also the ability to control the shapes, polarizations and directions of their …
