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 …

Plasmonic Nanostructures: Optical Nanocircuits, Tunable Charge Transfer Plasmons, and Properties of Fano Resonant Nanoclusters
… New interesting properties emerge, such as the Fano resonance, when clusters of nanoparticles are brought into close proximities. The reduced light scattering within the Fano resonance corresponds to the intense local fields around and within the clusters, a promising feature for the development …

Periodic subwavelength photonic structures
… was about 800. The third application is a Fano silicon photonic crystal modulator waveguide device. The resonant cavity of the modulator is a 1D photonic crystal cavity. If we excite the fundamental and first excited mode of the waveguide, we obtain a Fano resonance that can potentially …

FABRICATION METHODOLOGIES FOR INTEGRATED PHOTONIC DEVICES IN LITHIUM NIOBATE
… slabs were successfully fabricated and their Fano resonance phenomenon was systematically investigated for the first time. Both simulation and experimental results confirmed that such device has great potential for active integrated photonic circuits. Besides out-of-plane investigations, we …

High Resolution Distributed Sensing Using Exposed-Core Fibres
… excitation of spherical particles, where both Fano resonance and multi-particle (integrated in a single ECF) WGM excitation are demonstrated. The multi-particle WGM excitation opens opportunity to build multi-point sensors or lasers, and to study coupling effects resulting from multiple closely …

From fano to nano: mechanisms and applications of surface enhanced raman spectroscopy
… fields and when this involves a spectrally broad resonance and another narrower resonance, very sharp 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 …

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 …

Extreme electromagnetic phenomena over an ultrathin platform
… ultrafast and low loss analog signal processing. Fano resonance provides a strong nonlocality in transverse momentum space, which supports different types of mathematical operations near the speed of light. Furthermore, nonlinear meta-structures are studied to manifest a second harmonic generation …

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 …

Novel angular and frequency manipulation of light in nano-scaled dielectric photonic systems
… generation mechanism that produces colors by the Fano resonance effect on thin photonic crystal slab. We experimentally realize the proposed idea by fabricating the samples that show resonance-induced colors with weak dependence on the viewing angle. We also show that the colors can be dynamically …

Spectral properties of strongly correlated electron systems
… a combination of surface state dispersion and Fano resonance between surface state and the continuum of LEED-states may produce a precipitous drop in the observed photoelectron current as a function of in-plane momentum, which may well mimic a Fermi-surface crossing. This effect may explain the …
