Optical Gaussian Notch Filter Based on Periodic Microbent Fiber Bragg Grating
TL;DR: In this paper, an optical Gaussian notch filter was constructed from a periodic microbent fiber Bragg grating attained by using two copper-wire-wound slabs, which can be used as a Gaussian filter.
Journal ArticleDOI
Fiber optic salinity sensor using beam-through technique
Husna Abdul Rahman,Husna Abdul Rahman,Sulaiman Wadi Harun,Moh. Yasin,Moh. Yasin,Harith Ahmad +5 more
TL;DR: In this paper, a fiber optic displacement sensor is proposed to sense salinity based on different concentration of sodium chloride (NaCl) in de-ionized water using the beam-through technique.
Journal ArticleDOI
Multiwavelength generation using an add-drop microring resonator integrated with an InGaAsP/InP sampled grating distributed feedback
Sayed Ehsan Alavi,Iraj Sadegh Amiri,M. R. K. Soltanian,R. Penny,Abu Sahmah Mohd. Supa'at,Harith Ahmad +5 more
TL;DR: In this article, a system of an add-drop microring resonator integrated with a sampled grating distributed feedback (SG-DFB) is investigated via modeling and simulation with the TDTW method.
Journal ArticleDOI
Compact and flat-gain fiber optical amplifier with Hafnia-Bismuth-Erbium co-doped fiber
Alabbas A. Al-Azzawi,Aya A. Almukhtar,P. H. Reddy,P. H. Reddy,Debjit Dutta,Shyamal Das,Anirban Dhar,Mukul Chandra Paul,U.N. Zakaria,Harith Ahmad,Harith Ahmad,Sulaiman Wadi Harun,Sulaiman Wadi Harun +12 more
TL;DR: In this article, the authors demonstrated a compact Erbium-doped fiber amplifier (EDFA) using a newly developed Hafnia Bismuth erbium co-dope fiber (HBEDF) as a gain medium.
Journal ArticleDOI
Long-wavelength-band Er/sup 3+/-doped fiber amplifier incorporating a ring-laser as a seed signal generator
Mohd Adzir Mahdi,Harith Ahmad +1 more
TL;DR: In this paper, a dual-stage erbium-doped fiber amplifier with a gain-clamped amplifier based on a ring-laser feedback as a seed signal generator in the first stage is described.
