Abstract

In this paper, a water-filled D-shaped photonic crystal fiber (WFDSPCF) sensor based on the birefringence response for simultaneously measuring the liquid refractive index (LRI) and liquid temperature (LT) is proposed. We undertake theoretical and simulation calculations, and the results show that the proposed WFDSPCF can achieve ultrahigh LRI and LT sensitivities when operating around the group birefringence turning point. By optimizing the structural parameters, the proposed WFDSPCF sensor can achieve LRI and LT sensitivities of -25642.86 nm/RIU and 12.8 nm/°C, respectively. In addition, in order to eliminate the sensing crosstalk between the LRI and LT, a parallel Lyot interferometer structure is also proposed. The proposed WFDSPCF sensor is expected to have potential use in biochemical sensing, measurement science, and environmental monitoring.

基于充水 D 型光子晶体光纤的双折射响应同时测量液体折射率和温度

本文提出了一种基于双折射响应的充水 D 型光子晶体光纤（WFDSPCF）传感器，用于同时测量液体折射率（LRI）和液体温度（LT）。我们进行了理论和仿真计算，结果表明，当在群双折射转折点附近工作时，所提出的 WFDSPCF 可实现超高的 LRI 和 LT 灵敏度。通过优化结构参数，拟议的 WFDSPCF 传感器的 LRI 和 LT 灵敏度可分别达到 -25642.86 nm/RIU 和 12.8 nm/°C。此外，为了消除 LRI 和 LT 之间的传感串扰，还提出了一种平行 Lyot 干涉仪结构。所提出的 WFDSPCF 传感器有望用于生化传感、测量科学和环境监测。
