“…Metal-insulator-metal (MIM) structures can propagate SPPs at the subwavelength dimensions with light confinement properties [4]. So, these structures have been used in many applications such as Mach-Zehnder interferometers [5][6][7][8], Bragg reflectors [9,10], demultiplexers [11,12], sensors [13][14][15][16][17][18], modulators [19], filters [20,21], and optical switches [22,23]. Plasmonic filters based on the MIM waveguide structures provide effective solutions for comparatively high propagation loss due to large size [24].…”

In this work, multiple ultra-narrow band-stop filters based on metal–insulator–metal (MIM) plasmonic waveguide filters with high efficiency are designed and analyzed numerically. The relationship between incident radiation and transmission spectra is investigated between 0.45 μm and 1.5 μm in the electromagnetic spectrum by finite-difference time-domain (FDTD) method. The designed structures have a bus waveguide coupled with nanoring cavity resonators of different sizes. Minimum transmission is 1.3% at 622 nm. The full width at half maximum (FWHM) is 8.64 nm and the quality factor is obtained as 72.33 in this wavelength. The highest quality factor is 185.48 and the lowest FWHM is 4.2 nm at 779 nm. The designed waveguide-based filters can be used for integrated optical devices from visible to near-infrared regimes.

“…In 2020, Xiong et al designed a system based on a plasmonic photonic crystal and multimode cavities coupled to realize an ultra-narrowband multichannel filter [6]. In 2021, Feng et al designed a structure combining a double square ring and rectangle, which realized an efficient plasma waveguide filter [7]. The above-mentioned studies mainly focus on solid-size filters, which will not be able to change the structure-function once they are fabricated.…”

We propose a metal-insulator-metal (MIM) waveguide structure in which the plasma-induced transparency (PIT) effect is based. Using the finite-difference in time domain (FDTD) method, the designed structure was simulated in two dimensions. It obtains both narrowband PIT peaks, both with more than 90% absorption. In addition, we use the Kerr material filled in the cavity for tuning, and we can find that the transmission spectrum shifts with increasing pump light intensity. The proposed structure can be applied to filter. The proposed structure has important prospects for application in integrated optical devices.
