“…2,3 Fano resonances caused by destructive interference between narrow dark modes and broad bright modes in plasmonic nanostructures can suppress radiative damping effectively, [4][5][6][7][8][9][10][11] resulting in a narrow line width and strong near field enhancement, and the sensing performance characterized by figure of merit (FoM) can be significantly improved. [12][13][14][15][16][17] Near-field imaging of Fano resonances using interferometric near-field microscopy agree well with numerical calculations. 18 Multiple Fano resonances have also drawn a lot of attention because they can simultaneously modify the plasmon line at several spectral positions.…”

Double Fano resonances in nanoring cavity dimers: The effect of plasmon hybridization between dark subradiant modes

et al. 2014

Dark mode which is subradiant plays a key role in the generation of Fano effect. This study proposes that plasmon interaction between dark modes is a favorable method to generate multiple Fano resonances, where plasmon hybridization leads to the formation of a subradiant bonding and a subradiant antibonding combination. It demonstrates that a concentric ring/ring cavity dimer introduces interactions that render bonding quadrupolar ring mode dipole active, resulting in a pronounced Fano resonance. The corresponding antibonding quadrupolar ring mode is excited in a symmetry breaking nonconcentric cavity dimer, and double Fano resonances appear in the spectra.

We present a general input-output formalism for the few-photon transport in multiple waveguide channels coupled to a local cavity. Using this formalism, we study the effect of Fano interference in two-photon quantum transport. We show that the physics of Fano interference can manifest as an asymmetric spectral line shape in the frequency dependence of the two-photon correlation function.The two-photon fluorescence spectrum, on the other hand, does not exhibit the physics of Fano interference.

“…As shown in Figure 5(a), we have proposed a plasmonic sensor based on Fano resonance in a plasmonic waveguide-resonator system, which consists of a MIM waveguide coupled with a pair of nanoresonators. The geometrical parameters can be seen in [74]. The spectral features of plasmonic waveguide-resonator systems were investigated by the temporal coupled-mode theory [75].…”

Plasmonic waveguides that allow deeply subwavelength confinement of light provide an effective platform for the design of ultracompact photonic devices. As an important plasmonic waveguide, metal-insulator-metal (MIM) structure supports the propagation of light in the nanoscale regime at the visible and near-infrared ranges. Here, we focus on our work in MIM plasmonic waveguide devices for manipulating light, and review some of the recent development of this topic. We introduce MIM plasmonic wavelength filtering and demultiplexing devices, and present the electromagnetic induced transparency (EIT)-like and Fano resonance effects in MIM waveguide systems. The slow-light and rainbow trapping effects are demonstrated theoretically. These results pave a way toward dynamic control of the special and useful optical responses, which actualize some new plasmonic waveguide-integrated devices such as nanoscale filters, demultiplexers, sensors, slow light waveguides, and buffers. for SPP propagation. The unique features of MIM waveguides can be utilized to realize nanoscale photonic functionality and circuitry [11]. In this review, we mainly focus on our research about the manipulating properties in the MIM plasmonic waveguides. Due to the limit of this small topic, an amount of research in the plasmonic field will be omitted, for example, the important applications of SPPs for the enhancement of nonlinear effects [12], beam focusing [13,14], polarization analyzer [15], optical amplifier [16], and so on. We review some recent development of MIM plasmonic waveguide devices. Especially, plasmonic wavelength filtering and demultiplexing have been introduced. The analogue of electromagnetic induced transparency (EIT) and Fano resonances and their applications are presented in the MIM plasmonic waveguide systems. The slow light and rainbow trapping in the MIM waveguides are demonstrated. These results may provide some useful information for attracting researchers' interests in further investigation of the control of light and its applications in the plasmonic waveguides.
