光纤折射率（RI）传感器具有成本低、光学结构简单、可远距离传感和制作简单等优点。采用劈裂法、化学玻璃刻蚀法和电弧放电法依次制作出锥基圆结构，即锥结构和圆结构的组合结构。为了检验RI传感器的可能性，所制造的基于圆锥的圆形结构被用于通过测量目标感测介质中的反射强度来检测各种RI。此外，光纤局域表面等离子体共振（LSPR）传感器的基础上，基于圆锥形的圆形结构的制作，以提高有关RI变化的灵敏度。制作的光纤LSPR传感器用于检测使用峰值波长的移动，以及反射的共振强度的变化，通过测量其上的金纳米粒子的LSPR光谱的RI的变化。
Fiber-optic refractive index (RI) sensors have the advantages of low cost, simple optical setup, remote sensing, and simple fabrication. A cone-based round structure, which is the combined structure of the cone structure and the round structure, is successively fabricated by using a cleaving method, a chemical glass etching method, and an electrical arc discharge method. In order to examine the possibility of the RI sensor, the fabricated cone-based round structure is used for the detection of various RIs by measuring the reflected intensities in the target sensing media. In addition, a fiber-optic localized surface plasmon resonance (LSPR) sensor based on the cone-based round structure is fabricated to enhance the sensitivity regarding RI changes. The fabricated fiber-optic LSPR sensor is used to detect the change of the RIs using the shift of peak wavelengths, as well as the change of reflected resonance intensities, by measuring LSPR spectra for gold nanoparticles on it.
