The plasmonic bandpass and bandstop lter based on the Wilkinson power divider structure with the nanoring resonators are proposed and demonstrated. we nd that the resonance wavelengths can be manipulated by adjusting the inner radius and outer radius of the nanoring resonator. Using the manipulation of the gap size between the ring resonators and rectangular stubs the bandpass and bandstop lters were designed. When the angle between the input waveguide and ring resonators is changed, the rst mode is suppressed. The propagating modes of surface plasmon polaritons (SPPs) are investigated in this lter. The nite-difference time-domain (FDTD) method is utilized to investigate and analyze the transmission characteristics of the proposed lter. The proposed plasmonic lter is of a compact size that has potential application for integrated optics. The proposed technique can suppress the modes. The results show that the ltering wavelength can be manipulated by changing the stubs and rings parameters.

A structure is proposed in this article consisting of a stub metal–insulator–metal (MIM) waveguide coupled with an embedded T-shaped square ring resonator (ETSRR). The transmission characteristics and magnetic field distribution of the design are analyzed in detail using the finite element method (FEM). Furthermore, the geometric parameters are optimized using an improved genetic algorithm to enhance device performance. The proposed structure is therefore an ideal candidate for realizing a refractive index sensor and slow-light device, with potential applications in various fields such as sensing and communication. Moreover, our study provides valuable insights to the design of surface plasmon polarition (SPP) waveguides with computer assistance.

In this paper, a metal–insulator–metal waveguide structure is proposed based on a D-shaped resonator and a stub resonator, and it can generate multiple Fano resonances. The magnetic field (Z-direction) distribution and transmission spectrum of the structure are analyzed by the finite element method (FEM). The theory results are performed with the multimode interference coupled mode theory (MICMT), and they show high agreement with the simulation outcomes. The calculations also discuss the effect of structural parameters on the transmission spectrum. Moreover, the structure’s sensing characteristics are analyzed in detail, achieving a maximum sensitivity and FOM* of 1300 nm/RIU and 181.44, respectively. In addition, the slow light properties of the structure are also investigated, whose group delay and group index can reach 0.24 ps and 48.93, respectively. The group delay time is dynamically regulated by controlling the number of D-shaped resonators to achieve the effect of a delay line. It can provide some reference value for multifunctional on-chip optical integrated devices based on MIM waveguide structure.
