“…A two-dimensional view of the symmetrically designed optical plasmonic gates with an area of 300 nm × 300 nm is indicated in Figure 1. Symmetrical design supports strong absorption and scattering of light leading to enhance electromagnetic felds near the metal surface [45]. Te metal region is assumed to be silver with the dispersive relative permittivity characterized by Johnson and Christy's data [46].…”

This paper proposes a new configuration of dielectric-metal-dielectric (DMD) waveguides to design optical logic gates. Seven plasmonic logic gates, including NOT, OR, AND, NAND, NOR, XOR, and XNOR, are realized by one nanoring and four DMD plasmonic waveguides. To realize the logic gates, an ultrasmall size of 300 nm × 300 nm device is designed. The performance of the plasmonic logic gates is based on constructive and deconstructive interference between input and control ports. To evaluate the logic state of the output port, the threshold transmission limit is assumed to be 0.35. The transmission ratio, T, contrast ratio, CR, modulation depth, MD, insertion loss, IL, and contrast loss, CL, parameters measure the seven logic gates’ performance. A maximum T of 232% is obtained for AND, OR, and XNOR logic gates. Simulation results show that the dimensional parameters are optimized because of very high MD for all seven logic gates. Maximum values of CR and CL are obtained for the NOT gate. For the AND gate, a minimum IL value is achieved. The studied plasmonic logic gates can be employed in building blocks of all-optical signal-processing nanocircuits and nanophotonics devices. The finite element method (FEM) simulates the structure with COMSOL Multiphysics 5.4 software.

“…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.

“…Plasmonic WDMs are therefore essential components of communication networks [13]. Plasmonic MIM waveguides are extensively studied for several eye-catching applications such as filters [14][15][16][17], sensors [18][19][20], alloptical logic gates [21], and switches [22], among others. In [23], a 1 × 2 plasmonic wavelength demultiplexer is proposed based on a rectangular MIM waveguide that offers low crosstalk of 11.06 dB.…”

In this work, a numerical analysis of a compact 1 × 2 plasmonic demultiplexer based on a metal–insulator-metal (MIM) waveguide is presented. Two hollow circular cavities are side coupled to the bus waveguide on both sides. The cavities are designed in such a way that they resonate at the working wavelength of 1310 nm and 1550 nm. The mechanism of light coupling to an MIM waveguide has not been considered in previous studies. Therefore, a silicon tapered mode converter is integrated with a plasmonic demultiplexer for the efficient conversion of a dielectric to a plasmonic mode. The footprint of the device is 6 μm × 6 μm. The crosstalk at P1 and P2 is ~ 14.07 dB and ~ 13.67 dB for the transmission wavelength of 1310 nm and 1550 nm, respectively.
