“…The SLRs can be observed in nanoparticle pairs, [ 24 ] 1D chain, [ 59b ] 2D arrays, [ 29 ] and 3D structures. [ 61 ] The quality and the linewidth of SLRs generally depend on the array period, arrangement, array size, particle size, position or size disorder, and the surrounding medium, as shown in Figure . For example, the linewidth becomes sharp and pronounced by increasing the period, as shown in Figure 3a.…”

Subwavelength confinement of light with plasmonics is promising for nanophotonics and optoelectronics. However, it is nontrivial to obtain narrow plasmonic resonances due to the intrinsically high optical losses and radiative damping in metallic structures. In this review, a thorough summary of the recent research progress on achieving high‐quality (high‐Q) factor plasmonic resonances is provided, emphasizing the fundamentals and six resonant mode types, including surface lattice resonances, multipolar resonances, plasmonic Fano resonances, plasmon‐induced transparency, guided‐mode resonances, and Tamm plasmon resonances. The applications of high‐Q plasmonic resonances in spectrally selective thermal emission, sensing, single‐photon emission, filtering, and band‐edge lasing are also discussed.

“…Supported by metal nanostructures in the sub-wavelength range, LSPR has a large local electromagnetic field enhancement effect [ 1 , 2 ], to be applied to surface-enhanced Raman scattering [ 3 , 4 ], electromagnetic induction transparency (EIT) [ 5 , 6 , 7 ], and in other fields. However, its quality factor (Q-factor) is relatively low (Q < 10) [ 8 , 9 ] to achieve ultra-narrow-band resonance due to the excessively high ohmic loss of the metal, thus resulting in the impracticality of potential applications based on surface plasmon resonance. In recent years, a large number of studies have extensively conducted and deeply explored the optical nanodevices that excite ultra-high Q resonance lines to overcome this defect, mainly focusing on: the resonators of high refractive index dielectric materials related to bound or quasi-bound states in the continuum excite the Fano resonance of high Q-factor through strong coupling between modes [ 10 , 11 , 12 , 13 , 14 , 15 ], and the plasma lattice resonance and Fano resonance based on periodic structure [ 8 , 16 , 17 , 18 , 19 , 20 , 21 ].…”

We propose a high quality-factor (Q-factor) multi-Fano resonance hybrid metamaterial waveguide (HMW) sensor. By ingeniously designing a metal/dielectric hybrid waveguide structure, we can effectively tailor multi-Fano resonance peaks’ reflectance spectrum appearing in the visible wavelength range. In order to balance the high Q-factor and the best Fano resonance modulation depth, numerical calculation results demonstrated that the ultra-narrow linewidth resolution, the single-side quality factor, and Figure of Merit (FOM) can reach 1.7 nm, 690, and 236, respectively. Compared with the reported high Q-value (483) in the near-infrared band, an increase of 30% is achieved. Our proposed design may extend the application of Fano resonance in HMW from mid-infrared, terahertz band to visible band and have important research value in the fields of multi-wavelength non-labeled biosensing and slow light devices.

“…Moreover, in the lattice array, the electric field component of the incident light ( inc E ) can induce dipoles moment in each nanoparticle [18]. It sometimes exhibits as in-plane dipoles and out-of-plane quardrupoles due to their different polarizability, leading to retarded electric fields ( dipole E ) formed by the summing dipoles moment and inc E coexist in the array [19,20]. The coupling of two or more single nanoparticles and symmetry-breaking nanostructures has been extensively studied to enhance light-matter interactions.…”
