Abstract

It is shown that during the propagation of surface plasmon polariton (SPP) on a metal-coated tip of an optical fiber its wavelength essentially decreases and wave fields anomalously increase. Dependence of a degree of localization of SPP on sharpness of the structure and width of the metal layer is defined. The received results can be used to increase the resolution of scanning optical microscope.

摘要

结果表明，在表面等离激元极化激元（SPP）在光纤金属包覆尖端上传播的过程中，其波长显著减小，而波场异常增大。确定了SPP的局域化程度与结构锐度和金属层宽度的关系。所得结果可用于提高扫描光学显微镜的分辨率。
