Harith Ahmad,Amirah Abdul Latif,Siti Fatimah Norizan,Mohd Zamani Zulkifli,Sulaiman Wadi Harun +4 more
TL;DR: A dual-wavelength ytterbium doped fiber laser with a narrowest spacing of 0.53 nm and widest spacing of 12.2 nm at 1064 nm is presented in this paper.
Journal ArticleDOI
Gain-clamping in two-stage L-band EDFA using an unwanted backward ase from second stage
Sulaiman Wadi Harun,Harith Ahmad +1 more
TL;DR: In this article, a gain clamping technique for the long wavelength band erbium-doped fiber amplifier (L-band EDFA) is presented, which uses two circulators and a broad band fiber Bragg grating to route wasted backward C-band ASE from the second stage and launch it back into the first stage of a two-stage amplifier.
Journal ArticleDOI
Multi-wavelength Q-switched Erbium-doped fiber laser with photonic crystal fiber and graphene - Polyethylene oxide saturable absorber
TL;DR: In this article, a simple multi-wavelength passively Q-switched Erbium-doped fiber laser is demonstrated using graphene based saturable absorber, which is prepared using polyethylene oxide as a host polymer.
Journal ArticleDOI
Thulium Holmium-Doped Fiber Laser Mode-Locked Using Sb2Te3 Saturable Absorber Coated Arc-Shaped Fiber
TL;DR: In this article , the topological insulator antimony telluride (Sb2Te3) was used as a saturable absorber (SA) to obtain stable mode-locked pulses in a thulium holmium-doped fiber laser.
