“…Band-pass and band-stop filtering performance determine the quality of the applications (Cui et al 2023;Janfaza et al 2019;Korani et al 2023;Ebadi et al 2020;Pinton et al 2018;Mao et al 2017). There are many waveguide-based studies such as Mach-Zehnder interferometers (Swarnakar et al 2021;Yang et al 2022), modulators (Han et al 2022;Edelstein et al 2022), logic devices (Yang et al 2017;El Haffar et al 2022;Sreevani et al 2022;Swarnakar et al 2023), demultiplexers (Mohammadi et al 2023;Butt et al 2023), Bragg reflectors (Zeng et al 2022;Pallavi et al 2023), sensors (Bensalah et al 2022;Bahri et al 2022;Lai et al 2018;Salah et al 2021;Salah et al 2022) and directional couplers (Nanda et al 2022;Zhang et al 2020). The optical demultiplexer is based on the bandpass filter with its optimized parameters such as type and length of resonators.…”

Confinement of the light at the subwavelength scale makes photonic devices more efficient in applications such as optical filtering, switching, and sensing with their low dimensions. Metal-insulator- metal waveguide-based configurations present many paths for manipulating light at the wide range of the electromagnetic spectrum. For that purpose, in this study, a wavelength demultiplexer (WDM) based on a metal-insulator-metal (MIM) waveguide is numerically investigated by finite difference time domain (FDTD) method. Proposed WDMs have cascade polygon resonators. After optimizing the fundamental filter, this structure is formed as 1×N demultiplexers. The proposed demultiplexers have two- and three channels. The minimum full width at half-maximum (FWHM) value for these channels is 20.02 nm and the maximum quality factor value is 47.7 at 954.9 nm wavelength. The minimum crosstalk value is obtained as -30.37 dB for this study. The proposed 1×N demultiplexers have potential tools to design low-cost integrated optical circuits for specific wavelengths.

“…The one-bit and two-bit structures have footprints of 0.42 µm 2 and 0.9 µm 2 , respectively. In [26] a structure based on a MIM waveguide and having a footprint of 66 µm 2 was suggested for two combinational circuits. A pair of combinational logic functions that employed an IMI structure using an elliptical resonator with a size of 540 nm × 250 nm was suggested in [27].…”

The main purpose of this study is to design combinational logic gates based on a novel configuration of insulator–metal–insulator (IMI) nanoring plasmonic waveguides. Plasmonic logic gates are half adder, full adder, half subtractor, full subtractor, and one-bit comparator and are realized in one structure. The performance of the logic circuits is based on constructive and destructive interferences between the input and control signals. The transmission threshold value is assumed to be 0.35 at the resonance wavelength of 1.310 μm. The transmission spectrum, contrast loss (CL), insertion loss (IL), modulation depth (MD), and contrast ratio (CR) are calculated in order to evaluate the structure’s performance. The maximum transmission of the proposed structure is 232% for full a adder logic gate, and MD exceeds 90% in all plasmonic combinational logic circuits. The suggested design plays a key role in the photonic circuits and nanocircuits for all-optical systems and optical communication systems. The combinational logic gates are analyzed and simulated using the finite element method (FEM).
