Intensity based optical fiber sensors for calcium detection

TL;DR: In this paper, two optical fiber sensors are proposed and demonstrated for monitoring calcium concentration in a liquid solution, which is based on the peak voltage of the output which increases with the calcium concentration.
Journal ArticleDOI

Tapered fiber coated with hydroxyethyl cellulose/polyvinylidene fluoride composite for relative humidity sensor

TL;DR: In this article, a new evanescent wave based sensor is proposed and demonstrated using a silica fiber interferometer coated with Hydroxyethyl Cellulose/Polyvinylidene Fluoride (HEC/PVDF) composite.
Journal ArticleDOI

Generation of passively Q‐switched ytterbium laser by using tungsten tri‐oxide film absorber

TL;DR: In this paper, a Q-switched fiber laser using a new tungsten trioxide (WO 3)-based saturable absorber (SA) was demonstrated at the threshold pump power of 85mW with a repetition rate of 23.87 kHz and a pulse width of 5.56 μs.
Journal ArticleDOI

Temperature sensing by side coupling of light through zinc oxide nanorods on optical fibers

TL;DR: In this article, a temperature sensor fabricated by light side coupling through spirally patterned zinc oxide (ZnO) nanorods coated directly on plastic optical fiber (POF) is reported.
Journal ArticleDOI

Harmonic Dark Pulse Emission in Erbium-Doped Fiber Laser

TL;DR: In this article, a figure-of-eight configuration was used to generate a harmonic dark pulse in an erbium-doped fiber laser, which can be shifted from the fundamental to the 5th order harmonic by increasing the pump power with an appropriate polarization controller orientation.
