Abstract

We demonstrate the use of organic nanofibers, composed of self-assembled organic molecules, as a dielectric medium for dielectric-loaded surface plasmon polariton waveguides at near-infrared wavelengths. We successfully exploit a metallic grating coupler to excite the waveguiding mode and characterize dispersion properties of such waveguides using leakage-radiation microscopy.

摘要

我们展示了由自组装有机分子组成的有机纳米纤维作为近红外波长下介质加载表面等离子体激元波导的介电介质的应用。我们成功地利用金属光栅耦合器激发波导模式，并使用泄漏辐射显微镜表征此类波导的色散特性。
