Introducing tapered optical fibers into the structure to excite more evanescent waves improves the sensitivity of the sensor to the surrounding environment. In addition, due to the fact that
Abstract: In this paper, spectrally tailored tapered chirped fiber Bragg gratings (TCFBGs) are considered for use as strain sensors. Both gratings were written in fused tapered optical fiber
The strain sensor is constructed by fusing two standard single-mode optical fibers to form a microbubble and applying a taper on one side of the microbubble to form the asymmetric tapered structure.
Abstract and Figures A high-sensitivity strain sensor based on a Fabry–Pérot interferometer (FPI) with a tapered capillary structure is proposed and experimentally demonstrated.
In this article, a novel fiber-optic axial-strain sensor is proposed and demonstrated to improve the sensitivity based on the tapered-microfiber-assisted Mach-Z
In this paper, an in-line Mach-Zehnder interferometer based on the tapered thin-core fiber (t -TCF) structure is proposed to improve the response of axial strain. With varied diameters of
A high sensitivity sensor is proposed to measure axial strain, magnetic field, and refractive index. Hollow-core fiber (HCF) and single mode fiber (SMF) are fused together to form the
In this paper, a novel offset-core single micro-tapered fiber-optic MZI with a high strain sensitivity is proposed and experimentally demonstrated. This novel MZI is fabricated with ordinary
This study proposes an axial strain fiber-optic sensor based on the vernier effect. The sensor is composed of two tapered single-mode fibers (TSMFs) connected in parallel through two 3
In this paper, an in-line Mach-Zehnder interferometer based on the tapered thin-core fiber (t -TCF) structure is proposed to improve the response of
Fiber-optic sensors are optical sensors based on fiber devices. They are often used for sensing temperature and/or mechanical stress.
