Intensity based optical fiber sensors for calcium detection
Moh. Yasin,S. Soelistiono,Y. G.Yhun Yhuwana,Miratul Khasanah,Hamzah Arof,Ninik Irawati,Sulaiman Wadi Harun +6 more
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
Hazli Rafis Abdul Rahim,Hazli Rafis Abdul Rahim,Muhammad Quisar Lokman,Sulaiman Wadi Harun,Joydeep Dutta,Waleed S. Mohammed +5 more
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.
