Journal ArticleDOI
Chronology of Fabry-Perot interferometer fiber-optic sensors and their applications: a review.
TL;DR: A wide variety of FPI sensors are reviewed in terms of fabrication methods, principle of operation and their sensing applications in a study on interferometric optical fiber sensors.
Journal ArticleDOI
Experimental and theoretical investigations on water desalination using direct contact membrane distillation
TL;DR: In this article, an analytical model, based on the heat and mass transfer equations within the DCMD module, was used to predict the system performance at different operating conditions, and the model was validated with the experimental measurements.
Journal ArticleDOI
Towards 5G: A Photonic Based Millimeter Wave Signal Generation for Applying in 5G Access Fronthaul.
Sayed Ehsan Alavi,M. R. K. Soltanian,Iraj Sadegh Amiri,Mohsen Khalily,Abu Sahmah Mohd. Supa'at,Harith Ahmad +5 more
TL;DR: A photonic based simple and robust method for generating millimeter waves applicable in 5G access fronthaul is presented and the radio over fiber (RoF) system for transmission of orthogonal frequency division multiplexing (OFDM) with 5 GHz bandwidth is presented.
Journal ArticleDOI
Current sensor based on microfiber knot resonator
TL;DR: In this article, a microfiber knot resonator was used to tune the resonant wavelength inside a micro-fiber-cloth resonator with electric current applied to the copper wire, and the tuning was shown to be linearly proportional to the square of the amount of current.
Journal ArticleDOI
C-Band Q-Switched Fiber Laser Using Titanium Dioxide (TiO 2 ) As Saturable Absorber
Harith Ahmad,S.A. Reduan,Zainal Abidin Ali,M. A. Ismail,N.E. Ruslan,C.S.J. Lee,R. Puteh,Sulaiman Wadi Harun +7 more
TL;DR: In this paper, a passively Q-switched erbium fiber laser using titanium dioxide (TiO 2) as a saturable absorber was demonstrated, where the TiO 2 was fabricated as a polymer composite film and sandwiched between fiber ferrules.
