摘要

本文提出并设计了一种高灵敏度折射率（RI）传感器，它是一种在线马赫-泽恩德干涉仪（IMZI），带有光子晶体光纤（PCF）和通过电弧放电和锥形方法制造的多级微主轴结构。为了提高灵敏度，在 PCF 中插入了锥形多模光纤 (MMF)。对 RI 和温度检测的性能进行了分析和讨论。通过检测 NaCl 溶液，RI 灵敏度达到最大值 -2958.875 nm/RIU。此外，在 25 oC-65 oC 范围内，最大温度灵敏度为 6.4 pm/oC，温度引起的最大测量误差变化为 -0.0170‰/oC。这表明该传感器对 RI 非常敏感，但对温度不敏感。

A temperature-insensitive refractive index sensor based on in-line Mach–Zehnder interferometer with micro spindle structures and photonic crystal fibers

A high-sensitivity refractive index (RI) sensor is proposed and designed, which is an in-line Mach–Zehnder interferometer (IMZI) with a photonic crystal fiber (PCF) and multilevel micro spindle structures fabricated by the arc-discharging and tapering method. To improve the sensitivity, a tapered multimode fiber (MMF) is inserted into the PCF. The performance of RI and temperature detection has been analyzed and discussed. The maximum RI sensitivity of −2958.875 nm/RIU is achieved by detecting the NaCl solution. In addition, the maximum temperature sensitivity is 6.4 pm/

期刊介绍： Innovations in optical fiber technology are revolutionizing world communications. Newly developed fiber amplifiers allow for direct transmission of high-speed signals over transcontinental distances without the need for electronic regeneration. Optical fibers find new applications in data processing. The impact of fiber materials, devices, and systems on communications in the coming decades will create an abundance of primary literature and the need for up-to-date reviews. Optical Fiber Technology: Materials, Devices, and Systems is a new cutting-edge journal designed to fill a need in this rapidly evolving field for speedy publication of regular length papers. Both theoretical and experimental papers on fiber materials, devices, and system performance evaluation and measurements are eligible, with emphasis on practical applications.
