摘要

摘要报道了一种基于聚乙烯醇(PVA)涂层光子晶体光纤(PCF) -马赫-曾德干涉仪(MZI)的相对湿度传感器。通过将光子晶体光纤与两根单模光纤(smf)融合，并将融合区内光子晶体光纤的气孔完全折叠，作为分束器和耦合器，制备了传感结构。通过提升法，在光子晶体光纤上涂覆两到四层聚乙烯醇薄膜，表征其厚度对器件相对湿度灵敏度的影响。实验结果表明，在光子晶体光纤表面涂覆三层聚乙烯醇薄膜时，该相对湿度传感器的最大灵敏度为51.9 pm/%。

Monitoring relative humidity using a Mach-Zehnder interferometer (MZI) senor based upon a photonic crystal fiber (PCF) coated with polyvinyl alcohol (PVA)

Abstract A relative humidity (RH) sensor is reported based upon a photonic crystal fiber (PCF) – Mach-Zehnder interferometer (MZI) with a polyvinyl alcohol (PVA) coating. The structure for sensing was prepared by fusing photonic crystal fiber to two single-mode fibers (SMFs) and completely collapsing the air holes of photonic crystal fiber in the fusion area to act as the beam splitter and coupler. By a lifting method, two to four layers of polyvinyl alcohol films were coated upon the photonic crystal fiber to characterize the influence of its thickness upon the sensitivity of the device for relative humidity. The experimental results show that the maximum sensitivity of this relative humidity sensor is 51.9 pm/% when the photonic crystal fiber surface is coated with three layers of polyvinyl alcohol film.

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.
