在这篇文章中，一个新的和灵活的方法来控制蝴蝶结纳米天线的电场增强的锥形光纤的侧面集成他们提出。该器件由调Q激光驱动，并通过表面增强拉曼散射（Sers）实验测试了在石英载玻片中制造的纳米天线的性能。还进行了折射率传感实验，在1.33-1.35折射率范围内，发现（240 +/- 30）nm/RIU的灵敏度。(C)2017美国光学学会
In this article, a new and flexible approach to control the electric field enhancement of bow-tie nano-antennas by integrating them on the lateral of a tapered optical fiber is proposed. The device is driven by a Q-switched laser and the performance of a fabricated nano-antenna in a quartz slide is tested by a Surface Enhanced Raman Scattering (SERS) experiment. A refractive index sensing experiment is also performed and a sensitivity of (240 +/- 30) nm/RIU is found in the 1.33-1.35 index range. (C) 2017 Optical Society of America
