“…As seen, the proposed filter has one of the highest maximum transmission peaks. Although, some of the reported works including our other recent publications [24,25] have relatively higher maximum transmission peaks, but the designed structure in this paper has other advantages. The Q-factor of the proposed structure can be changed by increasing the number of the cavities.…”

“…Nonodisk cavities due to their easy implementation and tunable resonance frequencies are one of the most practical types of resonators for designing plasmonic filters. Accordingly, various plasmonic filters using nanodisk cavities have been designed [22][23][24][25][26]. Such structures are usually dual or multi-mode.…”

“…Its advantage is that by using the stub resonator, a narrow notch has been created at the transmittance spectrum. To obtain single-mode BPFs, CNCs coupled with parenthesis-shaped adjunctions can be used [24]. In [25], instead of a CNC, a hexagonal nanodisk cavity is used to improve the transmittance spectrum.…”

“…Although SSPPs are used in telecommunications for several applications like antennas [175][176][177] and transmission lines [178,179], they have shown an exceptional ability for highly efficient wavelength filtering [180,181]. Other filters' approaches include hexagonal [182,183] and ring resonators [184], as the one illustrated in Figure 4c, enabling easy tuning of rejection-band at mid-infrared frequencies by simply varying the ring's radius. In the case of hexagonal resonators, it can be easily coupled to a teeth-shape structure for single-mode filter applications [183].…”

Plasmonic materials, when properly illuminated with visible or near-infrared wavelengths, exhibit unique and interesting features that can be exploited for tailoring and tuning the light radiation and propagation properties at nanoscale dimensions. A variety of plasmonic heterostructures have been demonstrated for optical-signal filtering, transmission, detection, transportation, and modulation. In this review, state-of-the-art plasmonic structures used for telecommunications applications are summarized. In doing so, we discuss their distinctive roles on multiple approaches including beam steering, guiding, filtering, modulation, switching, and detection, which are all of prime importance for the development of the sixth generation (6G) cellular networks.

“…11,12 Many metal-insulator-metal (MIM) plasmonic devices based on SPPs have been recently introduced. Some of them include: plasmonic filters, [13][14][15][16] sensors, [17][18][19][20] splitters, 21,22 switches, [23][24][25] modulators, 26,27 slow-light waveguides, 28 and bit magnitude comparators. 29 Due to the vast attention and interest to optical demultiplexers (DeMuxes), a huge amount of studies have been directed on their realization.…”

Plasmonic demultiplexers using improved circular nanodisk resonators (CNRs) and metal-insulatormetal waveguides have been designed. The proposed structures use air and silver as insulator and metal layers, respectively. The relative permittivity of silver has been characterized by Drude, Palik, and Drude-Lorentz models in our finite-difference time-domain simulations. To obtain demultiplexers, first two filters based on improved CNRs are designed. One of the most outstanding features of a CNR is that the resonance wavelength can be tuned by changing its radius. It is shown that increasing the CNRs radii for the single-mode bandpass filter increases the resonance wavelength, linearly. Accordingly, double and triple-wavelength demultiplexers (DeMuxes) have been proposed for the wavelength range of 600 to 2000 nm. Due to their small area, the proposed demultiplexers can be applied in integrated optical circuits for optical communication purposes.
