“…Additionally, the suggested design can address the expanding need for faster speeds by transmitting data at a high speed of up to 103 Gb/s with higher CRs than other reported designs. 6,10,[16][17][18] From here, we deduce that specialists in the field are still working and will strive to find simpler and less cost designs that meet future needs. Following these significant efforts, we have designed compact SOI waveguides to perform seven basic Boolean logic functions, including XOR, AND, OR, NOT, NOR, NAND, and XNOR operated at a telecommunications wavelength of 1.33 μm.…”

.Silicon waveguides are particularly appealing for the implementation of all-optical (AO) signal processing devices and switches due to the improved fabrication technology of silicon. Therefore, a silicon-on-silica waveguide is employed as the building block for simulating fundamental AO logic operations, including XOR, AND, OR, NOT, NOR, NAND, and XNOR, at 1.33-μm telecommunications wavelength. The proposed waveguide consists of two microring resonators and three strip waveguides. The operation concept of these logic gates relies on the constructive and destructive interference that results from the phase difference induced by incident optical beams. The performance of the target logic gates is assessed against the contrast ratio (CR) metric. The simulation results suggest that, by exploiting the proposed waveguides, these gates can operate with higher CR and faster speed compared to other designs.

“…To attain the desired activation state on the output port, the all-optical logic gate's truth table determines how the incident wave's phase is regulated, resulting in different total losses. The waveguide losses are described in (3) [26].…”

In this paper, we report new nanoscale plasmonic multiple inputs logic gates based on insulator-metal-insulator (IMI) nanoring waveguides. The proposed all-optical gates are numerically analyzed by the finite element method. NOT, AND, NAND, NOR, and EX-NOR all-optical logic gates were suitably designed and investigated based on the linear interface between the propagated waves through the waveguides. The operation wavelength was 1550 nm. The simulation results show that the optical transmission threshold of (0.26) which performs the operation of planned logic gates is accomplished. Moreover, simulation results show that our compact structure of all-optical logic gates may have potential applications in all-optical integrated networks.

“…The second standard is optical power's contrast ratio (CR) in ON-OFF state at the output port that is described as shown in Table II [23], so when the difference in power is large, the performance of the gate is high. the following equation explains the mechanism for calculating the contrast ratio [16], [19].…”

“…Various plasmonic devices such as resonators [8], splitters [9], modulators [10], switches [11], [12], and logic gates [13], [14] were manufactured. Lots of studies have been created on logic gates, so different designs have been created made of different materials and with different geometric shapes and resonance frequencies, each design achieves a certain number of logic gates such as one design it's dimensions (2.4 µm × 3 µm) provides one logic gate when the wavelength is 850 nm [15], one design it's dimensions (760 nm × 600 nm) provides three logic gates when the wavelength is 1535 nm [16], two design their dimensions (1220 nm × 1120 nm) provide four logic gates when the wavelength is 525 nm [17], two design their dimensions (750 nm × 900 nm and 1.5 µm × 1.8 µm) provide three logic gates when the wavelength is 1535 nm [18], one design it's dimensions (400 nm × 400 nm) provides seven logic gates when the wavelength is 1550 nm [3], and one design it's dimensions (400 nm × 380 nm) provides seven logic gates when the wavelengths is 900 nm and 1330 nm [19]. In this paper, we suggest a new design with small dimensions (300 nm × 300 nm) that could achieve the seven logic gates (NOT, AND, OR, NAND, NOR, XOR, XNOR) where maximum transmission 134% at NOT gate, 223% at OR gate, 134% at NAND gate, and 223% at XNOR gate where the design is optimum design based on modulation depth equation and its resonance frequency at the wavelength of 1550 nm and with a transmission threshold 0.25 for all gates.…”

This paper displays a design that realizes all optical logic gates (NOT, AND, OR, NAND, NOR, XOR, XNOR) and consisting of one nanoring and four strips Operates on the principle of resonance. the proposed design works at the wavelength of 1550 nm using insulator-metal-insulator (IMI) plasmonic waveguide. The basic principle of the operation of these gates is input and control signals’ constructive and destructive interference. The proposed transmission threshold’s value is 0.25 between OFF state and ON state. The proposed design has small dimensions (300 nm × 300 nm) and can realize seven logic gates with maximum transmission 134% at NOT gate, 223% at OR gate, 134% at NAND gate and 223% at XNOR gate where the design is optimum and excellent design and the modulation depth is very high because it’s ranges in all gates more than 90%.
