Abstract

This paper introduces a nickel ion concentration sensor based on a cladding etched FBG with Chitosan/Dimethylglyoxime (CS/DmgH₂) sensing structure. The etching process of the FBG using HF is studied, and the CS/ DmgH₂ sensor structure is prepared on the etched CE-FBG using dip-coating and chemical precipitation methods. Experimental results demonstrate that the sensor has a sensitivity of 2.14 pm/µM within Ni²⁺ concentration range of 0–70 µM, exhibiting good linearity, stability, and reproducibility. Additionally, the experiments show that the sensor has specificity for Ni²⁺ sensing and good temperature sensitivity.

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.
