Abstract

In this paper, we present a Mach–Zehnder interferometer (MZI) sensor utilizing an optical fiber offset. The sensor core comprises multimode fiber (MMF), single-mode fiber (SMF), and offset no-core fiber (NCF), enabling it to detect the refractive index (RI) of liquids. The sensing mechanism of the sensor is theoretically analyzed, and various structural parameters are simulated, using the Beam Propagation Module (BPM). Simulation results indicate that the sensor efficiently operates across the entire wavelength range of 1.5–1.61 µm, providing continuous calibration curves for RI measurement. The sensor sensitivity to RI ranges of 1.3330–1.3340, 1.3334–1.3335, 1.3530–1.3540, and 1.3630–1.3640 are –14342, –14700, –17628, and –19600 nm/RIU, respectively. Additionally, the sensor exhibits a favorable linear response, laying a crucial foundation for developing the high-sensitivity liquid RI sensor design. The sensor boasts a simple, compact design, high sensitivity, and significant application potential in liquid RI measurements.

基于横向偏移结构的复合腔光纤MZI折射率传感器的理论研究
在本文中,我们提出了一种利用光纤偏移的马赫-曾德尔干涉仪(MZI)传感器。传感器芯包括多模光纤(MMF)、单模光纤(SMF)和偏置无芯光纤(NCF),能够检测液体的折射率(RI)。利用波束传播模块(BPM)对传感器的传感机理进行了理论分析,并对传感器的各种结构参数进行了仿真。仿真结果表明,该传感器在1.5-1.61 µm的整个波长范围内有效工作,为RI测量提供了连续的校准曲线。在1.3330-1.3340、1.3334-1.3335、1.3530-1.3540和1.3630-1.3640的RI范围内,传感器的灵敏度分别为-14342、-14700、-17628和-19600 nm/RIU。此外,该传感器具有良好的线性响应,为开发高灵敏度液体RI传感器设计奠定了重要基础。该传感器具有简单,紧凑的设计,高灵敏度,在液体RI测量中具有重要的应用潜力。
