“…The essential characteristic of surface plasmon polariton (SPP) is the ability to couple the electromagnetic waves to make the propagation of free electrons oscillations at the dielectric-metal interface [1]. Overcoming the diffraction limit problem makes the surface plasmon polariton (SPP) have a different application in highly integrated optical circuits [2]. Many all-optical devices in sub-wavelength have been proposed, such as switches [3], logic gates [4][5][6], modulators [6], sensors [7,8], and nanowires [9].…”

In this work, all-optical plasmonic NOT logic gate was proposed using Insulator-Metal-Insulator (IMI) plasmonic waveguides Technology. The proposed all-optical NOT gate is simulated and realized using COMSOL Multiphysics 5.3a software. Recently, plasmonic technology has attracted high attention due to its wide applications in all-optical signal processing. Due to its highly localization to metallic surfaces, surface plasmon (SP) may have huge applications in sub wavelength to guide the optical signal in the waveguides which results in overcoming the diffraction limit problem in conventional optics. The proposed IMI structure is consist of a dielectric waveguides plus metallic claddings, which guide the incident light strongly in the insulator region. Our design consists of symmetric nano-rings structures with two straight waveguides which based on IMI structure. The operation of all-optical NOT gate is realized by employing the constructive and destructive interface between the straight waveguides and the nano-rings structure waveguides. There are three ports in the proposed design, input, control and output ports. The activation of control port is always ON. By changing the structure dimensions, the materials, the phase of the applied optical signal to the input and control ports, the optical transmission at the output port is changed. In our proposed structure, the insulator dielectric material is glass and the metal material is silver. The calculated contrast ratio between (ON and OFF) output states is 3.16 (dB).

In this paper, a plasmonic logic device with the novel manipulation method is proposed. It consists of a hexagonal resonator in the center of the structure and dual rectangular resonators in which two sliders are embedded. The input states of the logic gate are represented by the positions of the slider. The temporal coupled-mode theory demonstrates that different positions of the slider lead to changes in the transmission spectra, which is the main idea in achieving logic operation. Ultimately, three logic operations (AND, XOR, and NOR) can be implemented simultaneously by moving the sliders and the finitedifference time-domain method is used for numerical validation. In addition, the influence of structural parameters on transmission characteristics and contrast ratio is also investigated. This paper is of great significance to the design of optical logic device on-chip and provides a new method for designing other integrated photonic devices.

In this work, all-optical plasmonic NOT logic gate was proposed by using metal-insulator-metal (MIM) plasmonic waveguides design. This logic gate is numerically analyzed by COMSOL Multiphysics 5.3a. Recently, plasmonics have attracted more attention due to its huge applications in all optical signal processing. Due to it’s highly localization to metallic surfaces, surface plasmon (SP) may have many applications in sub wavelength to guide the optical signal in waveguides to overcome the diffraction limit which considered a big problem in conventional optics. The proposed design of MIM structure is consist of a dielectric waveguides plus metallic claddings, which guide the incident light strongly in the insulator region. Strong localization and relatively simple fabrication make the MIM waveguides the potential key design of Nano-scale all optical devices. Our design consists of symmetric ring structures with straight waveguides which based on MIM structure. All-optical logic gate (NOT gate) behavior is achieved from utilizing the interface between straight waveguides and ring structure waveguides. By switching the activation of the control port, the propagation of the outgoing field in the output waveguide will be changed. As the simulation results show, the proposed structure could operate as an all-optical NOT logic gate. This gate would be a potential component in many applications of all-optical signals processing.
