Abstract
In this paper, a novel fiber-optic axial-strain sensor based on a micro-cavity Fabry-Perot interferometer (FPI) is proposed and experimentally realized. This micro-cavity FPI is mainly composed of a micro-air-bubble in a tapered hollow-core fiber fabricated by arc-discharged multiple-tapering technique. The experimental results show that the maximum sensitivity of axial-strain can reach ∼8.9 p.m./με in the range from 0 to 1100 με with high linearity. Additionally, high repeatability and ultra-low crosstalk of temperature (∼0.078 με/°C) are demonstrated, which brings a detection accuracy of 1.5 %. With the merits of compactness, low cost and ease of fabrication, the proposed sensor is very promising and potential to high precision axial-strain related measurement.
期刊介绍：
Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
