We present a comprehensive numerical analysis of the guiding of a photonic signal in the form of a strongly confined asymmetric surface plasmon polariton (SPP) mode along metallic nanowire waveguides. The proposed approach provides extremely high localization of the SPP mode, nanoscale integration density, and a feasible technological platform. The waveguide performance was studied over a broad range of subwavelength cross sections at a telecommunication wavelength. It was optimized using a conventional figure of merit for data transfer along a straight waveguide and an all-inclusive figure of merit has been introduced.
我们提出了一种对沿金属纳米线波导传播的强约束非对称表面等离子体激元（SPP）模式的光信号引导进行全面数值分析的方法。所提出的方法提供了极高的 SPP 模式局域性、纳米级集成密度和可行的技术平台。在电信波长下，对亚波长横截面的广泛范围进行了波导性能研究。使用传统的沿直波导传输的数据传输优值和综合优值对其进行了优化。
