Abstract

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).

摘要

本研究的主要目的是基于绝缘体 - 金属 - 绝缘体（IMI）纳米环等离子体波导的新型结构设计组合逻辑门。等离子体逻辑门包括半加器、全加器、半减器、全减器和一位比较器，并在一种结构中实现。逻辑电路的性能基于输入信号与控制信号之间的相长干涉和相消干涉。在1.310μm的共振波长处，传输阈值假定为0.35。为了评估该结构的性能，计算了传输光谱、对比度损失（CL）、插入损耗（IL）、调制深度（MD）和对比度（CR）。对于全加器逻辑门，所提出结构的最大传输率为232%，并且在所有等离子体组合逻辑电路中MD均超过90%。所建议的设计在用于全光系统和光通信系统的光子电路和纳米电路中起着关键作用。使用有限元方法（FEM）对组合逻辑门进行了分析和模拟。
