We present the development and study of a single bowtie nano-aperture (BNA) at the end of a monomode optical fiber as an interface between near-fields/nano-optical objects and the fiber mode. To optimize energy conversion between BNA and the single fiber mode, the BNA is opened at the apex of a specially designed polymer fiber tip which acts as an efficient mediator (like a horn optical antenna) between the two systems. As a first application, we propose to use our device as polarizing electric-field nanocollector for scanning near-field optical microscopy (SNOM). However, this BNA-on-fiber probe may also find applications in nanolithography, addressing and telecommunications as well as in situ biological and chemical probing and trapping.
我们展示了一种单模光纤末端的单蝴蝶结纳米孔径（BNA）的开发与研究，该BNA作为近场/纳米光学物体与光纤模式之间的接口。为了优化BNA与单光纤模式之间的能量转换，BNA在特殊设计的聚合物光纤尖端的顶点处开口，该尖端充当两个系统之间的有效介质（如喇叭形光学天线）。作为首个应用，我们提议将我们的设备用作扫描近场光学显微镜（SNOM）的极化电场纳米收集器。然而，这种光纤上的BNA探针也可能在纳米光刻、寻址和电信以及原位生物和化学探测与捕获中找到应用。
