Journal ArticleDOI
High sensitivity SMS fiber structure based refractometer – analysis and experiment
TL;DR: It is shown that the MMFC diameter has significant influence on the refractive index (RI) sensitivity but the length does not, and a refractometer with a lower MM FC diameter has a higher sensitivity.
Journal ArticleDOI
Investigation on Single-Mode–Multimode– Single-Mode Fiber Structure
Qian Wang,Gerald Farrell,Wei Yan +2 more
TL;DR: In this article, a single-mode-multimode-single-mode fiber structure is investigated and a simple way to predict and analyze the spectral response of the structure is presented through the space to wavelength mapping with the derived approximated formulations.
Journal ArticleDOI
All-fiber multimode-interference-based refractometer sensor: proposal and design
Qian Wang,Gerald Farrell +1 more
TL;DR: A novel all-fiber refractometer sensor is proposed, which is based on multimode interference in the multimode fiber core section sandwiched between two single-mode fibers, based on wide-angle beam propagation method in the cylindrical coordinate.
Journal ArticleDOI
High-sensitivity, evanescent field refractometric sensor based on a tapered, multimode fiber interference
TL;DR: An enhanced evanescent field fiber refractometer based on a tapered multimode fiber sandwiched between two single-mode fibers offers ultrahigh sensitivity and is the highest value reported to date (to the authors' knowledge) in the literature.
Journal ArticleDOI
Overview of Fiber Optic Sensor Technologies for Strain/Temperature Sensing Applications in Composite Materials
TL;DR: An overview of the different types of FOS used for strain/temperature sensing in composite materials and their compatibility with and suitability for embedding inside a composite material is presented.
