“…Thus, for axially polarized incident light (h = 90°), different kinds of higherorder multiple Fano resonances with large modulation depths are achieved, which are greatly useful for broadband biosensor and plasmon line shaping applications. Moreover, the large modulation depth of the Fano resonances can be used to produce slow light [16]. It is also observed that for all the values of h, Model III resonator is insensitive of the gap g because the nanoparticles are arranged in such a way that metal to metal interaction is very small.…”

“…The Model II resonator offers single Fano resonance for all values of h, which is not significant for broadband biosensor and plasmon line shaping applications. Also, the Fano resonance suffers from weak modulation depth, so extreme dispersion is not created which can help to produce slow light [16].…”

“…In such systems, Fano resonance arises due to the spectral overlapping of broad superradiant and narrow subradiant plasmon modes, which are usually characteristics of dipolar and higher-order plasmon modes, respectively. In contrast to symmetric Lorentzian line shape, the plasmonic devices based on the asymmetric Fano line shape have shown great sensitivity and large figure of merit (FoM), which can be used in high-performance biosensors, lasing, switching and slow light devices [13][14][15][16].…”

The optical properties of a nanodimer composed of hollow nanocylinders that are located in a close proximity to each other are investigated. The plasmon modes of the dimer resonator spectrally overlap and induce plasmonic Fano resonances due to destructive interference. For the generation of multiple Fano resonances with large modulation depths and sharp linewidths, several configurations of the dimer nanostructure are analyzed. Different kinds of unique Fano resonances are obtained by changing the polarization of incident light. Moreover, the spectral positions and modulation depths of the higherorder multiple Fano resonances can be flexibly tuned and controlled in the extinction spectrum by varying the geometrical parameters. The proposed resonator has the advantage to exhibit multiple Fano resonances with large modulation depths and offers high values of figure of merit and contrast ratio due to which it can be greatly appropriate for plasmon line shaping, slow light and broadband biosensing applications.

“…The characteristics of the single ring resonator have been widely investigated before [24], [36], and it typically exhibits broadband transmission spectra with nearly symmetric Lorentzian-like line-shapes [24], [26]. In the proposed structure, another groove is added between the bus waveguide and the ring resonator.…”

“…Previous works showed the plasmon induced transparency (PIT) based sensor can be fabricated in metamaterial [7], and the PIT sensor performs better than the non-PIT one due to the steeper variation in the optical spectrum [10]. In addition, the PIT system possesses slow-light that can enhance the lightmatter interaction, which can be used in sensors and slow-light devices [11,12].…”

We report the sensing characteristic based on plasmon induced transparency in nanocavity-coupled metal-dielectric-metal waveguide analytically and numerically. A simple model for the sensing nature is first presented by the coupled mode theory. We show that the coupling strength and the resonance detuning play important roles in optimizing the sensing performance and the detection limit of sensor, and an interesting double-peak sensing is also obtained in such plasmonic sensor. In addition, the specific refractive index width of the dielectric environment is discovered in slow-light sensing and the relevant sensitivity can be enhanced. The proposed model and findings provide guidance for fundamental research of the integrated plasmonic nanosensor applications and designs.
