ABSTRACT

In this paper, we propose a photonic crystal fiber (PCF) refractive index (RI) sensor based on the surface plasmon resonance (SPR) effect. The coupling and sensing characteristics of the proposed PCF-SPR RI sensor are investigated by the finite element method. The proposed PCF-SPR RI sensor can achieve the dual-wavebands measurement. By controlling the analytes height and incident light wavelength, the PCF-SPR RI sensor shows different sensing performances. The maximum wavelength sensitivities of the proposed PCF-SPR RI sensors can be up to 2000 and 4000 nm/RIU in the wavelength ranges of 0.75 to 1.0 and 1.2 to 2 μm, respectively.

摘要

在本文中,我们提出了一种基于表面等离子共振 (SPR) 效应的光子晶体光纤 (PCF) 折射率 (RI) 传感器。通过有限元方法研究了所提出的 PCF-SPR RI 传感器的耦合和传感特性。所提出的PCF-SPR RI传感器可以实现双波段测量。通过控制分析物的高度和入射光波长,PCF-SPR RI 传感器显示出不同的传感性能。所提出的 PCF-SPR RI 传感器的最大波长灵敏度分别在 0.75 到 1.0 和 1.2 到 2 μm 的波长范围内可以达到 2000 和 4000 nm/RIU。
