“…The resonance modes inside nanodisk can be easily inhibited and separated by adding a segment of waveguide at the input/output waveguide. Our results are better about 30% than that of the structure in Ref [2]. The mechanism of our scheme is based on the near-field coupling between nano-disk resonators and MIM waveguide, which is different from that of the scheme [7] based on the phase coupling and multiple electromagnetically induced transparencies (EIT)-like spectral responses in graphene metamaterials consisting of a series of self-assembled graphene Fabry-Pérot (FP) cavities.…”

“…Wavelength demultiplexers (WDMs), which can filter specific wavelengths in different channels, will play very important role in the all-optical systems [36]. Based on MIM coupled resonators, some WDM structures were proposed [37][38][39][40][41][42][43]. Noual et al [37] reported two-dimensional nanoscale Y-bent plasmonic waveguides with nanocavities for demultiplexing of the telecommunication wavelengths.…”

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.

“…Due to its unique characteristics including the strong confinement of optical field in nano-scale gaps, the high sensitivity of its transmission characteristics to the waveguide structures, and the facility of its fabrication, the MIM waveguide has attracted a great deal of effort in the fields of waveguide couplers [13], [14], sub-wavelength scale light confinement [15], [16], wavelength filters [17], [18], and integrated optical devices [19], [20]. Recently, numerous studies have been taken out to investigate the plasmonic resonators such as the plasmonic stubs [21]- [23], nano-capillary resonators [24], side-coupled FabryPerot [25], [26], high-performance wavelength demultiplexer [27], ultrafast all-optical switching [28], tunable high-channelcount bandpass filters [29], and slot cavities [30]- [34]. Ring resonator structure with circular or rectangular geometries is the mostly commonly used type of plasmonic resonators [35]- [40].…”

Abstract-We proposed a nanoplasmonic optical filtering technique based on complementary split-ring resonator structures. Interestingly, the proper plasmonic modes of the nanoring in the side-coupled arrangement can be selected and excited by the proposed structures. It is observed that the non-integer modes can be excited due to the presence of a metallic nano-wall as well as the integer modes. Furthermore, the numerical results indicate that the optical transmission spectrum of the investigated filter can be efficiently modified and tuned by manipulation either the position or the width of the employed nano-wall inside the metal-insulator-metal ring. The antinodes of the magnetic field of these modes, located on the symmetry plane of the proposed structures, can be manipulated by the position of the wall. Additionally, these modes, in particular the fundamental mode, are highly sensitive to the nano-wall dimensions. It indicates that the proposed nanofilter is a promising candidate as a tunable filter in nanophotonics applications.
