In this article, we demonstrated the minimum significant dielectric thickness of silicon dioxide (SiO2) below the diffraction limit for the confinement in the metal–insulator–metal (MIM) waveguide and utilizing this idea, we further exhibited the detail design analysis of dual‐band plasmonic meandering step impedance resonator (MSIR), which can achieve a high quality‐factor compared to a traditional step impedance resonator (SIR). MSIRs have sharper wavelength selectivity compared to SIRs, making them more suitable for applications that require precise wavelength tuning. The tunability of reflection and transmission characteristics with respect to design parameters has been reported. The designed MSIR has demonstrated a good passband response at wavelengths λ = 1414‐nm (E‐band) and 1577‐nm (L‐band) as well as turnability with design parameters. This filter achieved a large frequency spectral range of 139 nm and a high Q factor of ~3 × 104. This work enhances the capability of on‐chip filtering in the plasmonic platform.

“…As light waves interact with free electrons on a metal surface, specific surface waves are created at the interface between the two media [1][2][3]. These waves cause a phenomenon known as the surface plasmon polariton, which uses the basic functions of optical devices [4][5][6][7]. These surface waves can break the diffraction limit [8], allowing light to flow in waveguides of subwavelength dimensions.…”

Optical D and T flip flops are designed using hybrid plasmonic waveguides • The suggested design has nano dimensions of 400 nm 2 • There is an amplification effect in the Transmission values Surface waves are electromagnetic waves propagating along the interface between a metal and an insulator. Surface waves break the diffraction limits and enable light to propagate in sub-wavelength structures. That opens the field of electroopto devices. The main drawbacks of surface waves that move in the Plasmonic Waveguides (PWs) are propagation loss and low light confinement. Using a combination of the plasmonic waveguide and a Dielectric Waveguide (DW), the defect of the surface waves can be enhanced, and the Hybrid Plasmonic waveguide (HPW) is introduced. In this research, the design of an all-optical flip flop with 400 nm × 400 nm nano-scale dimensions, 1310 nm operating wavelength, and a transmission threshold (Tthreshold) of 30% is shown using hybrid plasmonic waveguides (HPWGs) for Electro-Opto applications. It offers the basic structure for creating optical computers. The results of this structure are evaluated in a term of Contrast Ratio (CR), Modulation Depth (MD), and Insertion Losses (IL). The D-flip flop had an Insertion Loss of -1.4 dB, a CR of 7.45 dB, and a MD of 97.67%. The T-flip flop had an IL of -2.07 dB, a CR of 11.2 dB, and a MD of 95.29%. The mechanism that governs the operation of the suggested circuits depends on the constructive and destructive interferences between input ports and control ports. The simulation is based on the finite element method utilizing COMSOL software package version 5.5.

“…On-chip half and full adders with a high CR, ultra-compact dimensions, and low threshold power, based on nonlinear plasmonic nanocavities have been experimentally developed [18]. Four optical combinational circuits with high transmission values based on square-shaped resonators and hybrid plasmonic waveguides have been introduced [24]. One-bit and two-bit comparators with high CR levels using two structures based on graphene waveguides have been designed [25].…”

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).
