Abstract
A refractive index (RI) and liquid level sensing scheme based on a multimode-no-core fiber tip with high sensitivity and precision is proposed and experimentally demonstrated by fusing a tapered no-core fiber (NCF) with a segment of multimode fiber. A gold film is plated on the side surface of the uniform waist region of the tapered NCF to stimulate surface plasmon resonance. The as-fabricated sensor achieves RI sensitivities of 16500 and 24000 nm/RIU (refractive index unit) in the RI ranges of 1.34 to 1.38 and 1.39 to 1.41, respectively. High-precision liquid level sensing with a range from 0.1 to 2.0 mm is obtained simultaneously. The designed sensing structure in this work offers simplicity and ease of implementation, which makes it a promising option for high-sensitivity and high-precision sensing applications.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
