Tunable wavelength generation in the 1 µm region incorporating a 16-channel arrayed waveguide grating (AWG)
M.A.M. Salim,M.A.M. Salim,Harith Ahmad,Saaidal Razalli Azzuhri,M.Z.A. Razak,Sulaiman Wadi Harun +5 more
TL;DR: In this paper, a 16-channel arrayed waveguide grating was proposed and demonstrated for a tunable single and dual-wavelength ytterbium-doped fiber laser.
Journal ArticleDOI
Multi-lobed double-clad Erbium-Ytterbium co-doped Q-switched fiber laser based on nonlinear polarisation rotation technique
I M Babar,M B S Sabran,Ahmad Fadzli Nizam Abdul Rahman,Mazani Manaf,Harith Ahmad,Sulaiman Wadi Harun +5 more
TL;DR: In this paper, the authors demonstrate a stable passive Q-switched fiber laser operating at 1543.5 nm using a double clad Erbium-Ytterbium co-doped fiber (EYDF) as the gain medium in conjunction with nonlinear polarization rotation (NPR) technique.
Journal ArticleDOI
Tunable Spacing Dual-Wavelength Q-Switched Fiber Laser Based on Tunable FBG Device
Nurnazifah M. Radzi,Amirah Abdul Latif,Mohammad Faizal Ismail,Josephine Ying Chyi Liew,Noor Azura Awang,Han K. Lee,Fauzan Ahmad,Siti Fatimah Norizan,Harith Ahmad +8 more
TL;DR: In this article, a tunable spacing dual-wavelength Q-switched fiber laser is experimentally demonstrated based on a fiber Bragg grating tunable device incorporated in an erbium-doped fiber laser.
Journal ArticleDOI
Theoretical and experimental studies on concave mirror‐based fiber optic displacement sensor
TL;DR: In this article, a concave mirror-based fiber optic displacement sensor performance for three-axes directional measurements was investigated, theoretically and experimentally, and the results showed that the focal length and radius of the concave reflector make significant influence to the displacement response.
Journal ArticleDOI
In-fiber Fabry Perot interferometer with narrow interference fringes for enhanced sensitivity in elastic wave detection
Muhammad Khairol Annuar Zaini,Yen-Sian Lee,N. Ismail,Kok-Sing Lim,Waldo Udos,Mohd Hafizi Zohari,Hangzhou Yang,Harith Ahmad +7 more
TL;DR: In this paper, a pair of in-fiber Fabry-Perot interferometer (FPI) with matched Bragg wavelength and free spectral range (FSR) was used for elastic wave detection based on matched filter interrogation configuration.
