“…For instance, a parallel LC resonator can be implemented using an SRR, as reported in [16], while impedance inverters can be realized using asymmetric parallel coupled MIM waveguide section. The physical dimensions can be obtained using fullwave simulations [27]. As a result, designed filters with compact configurations can be obtained.…”

In this work, an ultra-wideband (UWB) optical bandpass filter (BPF) based on nanoplasmonic structure is designed and thoroughly analyzed. The proposed BPF structure encompasses asymmetric metalinsulator-metal (MIM) slot waveguide that incorporates a gap-coupled series and parallel square ring resonators (SRRs). The characteristic parameters of the MIM waveguide structure are analyzed with a full-wave analysis and a conformal mapping technique (CMT) using a CAD simulation software. These include the normalized propagation constant, the propagation length, and the characteristic impedance. The UWB feature of the proposed structure is mainly dictated by the coupling gaps that combine the feed line with the resonators. Increasing the sequential number of the coupled resonators enhances the optical UWB feature of the proposed design. Two structures with three and five resonators are presented to illustrate the UWB characteristics within the 1235.74-1942 nm, and 1340-2200 nm ranges, respectively. In both cases, the return loss is shown to be higher than 10dB. The proposed nanoplasmonic UWB filter in this work has the potential to replace narrow-bandwidth devices involved in multi-band transmission systems and highdensity photonic integrated circuits. The outcomes of this research contribute to the advancement of UWB filter technology for next-generation communication systems and photonics.

Nanoplasmonic antennas are the one of the major elements in the recognition of upcoming nanoscale wireless communication systems. In this paper, the design and analysis of two multiband antennas operating at optical bands O and L bands, using metal-insulator-metal (MIM) slot waveguide based step impedance resonators (SIRs) and coplanar waveguide (CPW) fed line has been investigated. The simulation results of the two antennas (A) and (B) are obtained by using full wave simulation software (CST Microwave Studio Suite) with the return loss −20 dB and −30.79 dB at desired optical bands. The antenna (A) has a gain of 8 dBi and 7.48 dBi at 1275 nm and 1616 nm wavelengths, similarly antenna (B) has a gain of 8.46 dBi and 6.23 dBi at 1294 nm and 1613 nm wavelengths. The radiation pattern of the simulated results shows the omnidirectional pattern at desired wavelengths, which is very useful for nanoscale wireless communication systems.

This paper reports the design and numerical results of three new extremely compact and efficient flat-top band-pass plasmonic filters operating in the near-infrared region. The proposed structures are realized in metal–insulator-metal plasmonic waveguides based on stub, tilted T-junction and right-angle trapezoid configurations. A built-in parameterized genetic algorithm is applied to maximize the transmission efficiency, while at the same time contributing to shrinking down the size of the device structures. It is shown that the tunability of the optical filters can be realized by modulating their structural parameters to gain control over the band-pass filtering wavelengths. Numerical calculations are conducted based on the finite element method of CST Microwave Studio and demonstrate that the suggested ultra-compact plasmonic waveguide filters offer wide bandwidths of more than 270 nm, 424 nm, and 289 nm, with transmission efficiencies of higher than 80%, 74.2%, and 74.3%, respectively. The sizes of the proposed wavelength filters are 490 nm × 575 nm, 350 nm × 180 nm, and 420 nm × 150 nm, respectively, which make them attractive candidates for applications in high density photonic integrated circuits (PICs). As a result, because of the promising characteristics of the proposed topologies such as their high efficiency, compact size, tunability, and simple structure they may find applications in on-chip integration, laser technology, and multi-photon fluorescence.
