Fiber–optic sensors have been widely deployed in various applications, and their use has
gradually increased since the 1980 s. Distributed fiber–optic sensors, which enable …

A sensitivity-amplifying optical fiber sensor using cascaded Sagnac interferometers (CSIs)
was designed and experimentally demonstrated for the dual-parameter measurement of …

In the present study, we have theoretically proposed a novel sensing tool based on a
polymer defective one dimensional photonic crystal for highly accurate and sensitive …

A novel fiber curvature sensor without temperature cross interference based on a single hole
twin eccentric core fiber has been proposed. Anti-resonant mechanism combined with inline …

In this paper, a sensing interrogation system for fiber-optic interferometer type of sensors by
using a single-passband radio-frequency (RF) filter has been proposed and experimentally …

A configuration based on a parallel double Fabry-Perot interferometers (FPIs) is proposed
and experimentally demonstrated to enhance the temperature sensitivity by Vernier-effect …

A multi-components interferometer based on partially filled dual-core photonic crystal fiber
(DC PCF) was fabricated for measuring temperature and strain. The partially filled DC PCF …

A highly sensitive optical fiber strain sensor is presented in this work. The structure of the
device consists of cascaded multimode fiber (MMF) and photonic crystal fiber (PCF), fusion …

We demonstrated a fiber in-line Mach-Zehnder interferometer (MZI) coated with platinum (Pt)
for the simultaneous measurement of strain and temperature. The sensor was fabricated by …

A demodulation method for interferometric fiber sensors (IFSs) is proposed in this article.
The phase variation induced by the measurands can be estimated by calculating the Fourier …
