Abstract

Abstract This paper reports a double-sided polished microstructured fiber based on the refractive index that simultaneously measures the refractive index and temperature. Two polished planes were introduced into the cladding. A gold film and polydimethylsiloxane are deposited on one side of the plane for temperature measurements, and graphene layers are coated on the surface of the silver film on the other side for refractive index measurements. The finite element method is used to characterize the sensing characteristics of the sensor. The results show that when the liquid refractive index is from 1.36 to 1.4 and the temperature from 70 °C to 110 °C, the maximum sensitivity of the sensor is 15,000 nm/RIU and 8.8 nm/°C, respectively. The double-sided polished structure facilitates the development of multi-parameter measurement sensors for various applications.

基于双面抛光微结构光纤的用于折射率和温度测量的表面等离子体共振传感器

本文报道了一种基于折射率的双面抛光微结构光纤，该光纤可以同时测量折射率和温度。两个抛光平面被引入到包层中。在平面的一侧沉积一层金膜和聚二甲基硅氧烷，用于温度测量，在另一侧的银膜表面涂上石墨烯层，用于折射率测量。采用有限元法对传感器的传感特性进行了表征。结果表明，当液体折射率为1.36 ~ 1.4，温度为70 ~ 110℃时，传感器的最大灵敏度分别为15,000 nm/RIU和8.8 nm/°C。双面抛光结构便于开发各种应用的多参数测量传感器。

期刊介绍： Instrumentation Science & Technology is an internationally acclaimed forum for fast publication of critical, peer reviewed manuscripts dealing with innovative instrument design and applications in chemistry, physics biotechnology and environmental science. Particular attention is given to state-of-the-art developments and their rapid communication to the scientific community. Emphasis is on modern instrumental concepts, though not exclusively, including detectors, sensors, data acquisition and processing, instrument control, chromatography, electrochemistry, spectroscopy of all types, electrophoresis, radiometry, relaxation methods, thermal analysis, physical property measurements, surface physics, membrane technology, microcomputer design, chip-based processes, and more. Readership includes everyone who uses instrumental techniques to conduct their research and development. They are chemists (organic, inorganic, physical, analytical, nuclear, quality control) biochemists, biotechnologists, engineers, and physicists in all of the instrumental disciplines mentioned above, in both the laboratory and chemical production environments. The journal is an important resource of instrument design and applications data.
