Abstract

We propose and investigate theoretically and experimentally L-shaped gap surface plasmon waveguides (L-GSPWs) formed by a dielectric film (strip) partially enclosed between two metal films. The proposed L-GSPWs combine the benefits of strong plasmon localization in a nanogap, significant propagation distance, low cross-talk between two neighboring waveguides, high transmission through a sharp 90° bend, and simplicity of fabrication by means of the standard lithography combined with the thin film deposition.

摘要

我们提出并理论和实验研究了由部分夹在两个金属膜之间的介电膜（条）形成的 L 形缝隙表面等离子体波导（L-GSPW）。所提出的 L-GSPW 结合了纳米间隙中强等离子体局域、显著传播距离、两个相邻波导之间低串扰、通过尖锐 90°弯曲的高传输以及通过标准光刻与薄膜沉积相结合的简单制造的优点。
