Journal ArticleDOI
Four-wave mixing in zirconia-erbium doped fiber ? a comparison between ring and linear cavities
Harith Ahmad,K. Thambiratnam,Noor Azura Awang,Noor Azura Awang,Z.A. Ghani,Sulaiman Wadi Harun +5 more
TL;DR: In this article, the authors compared linear and ring cavities for the generation and performance of the four-wave mixing (FWM) effect in zirconia-erbium doped fibers (Zr-EDFs).
Journal ArticleDOI
Mode-locked thulium/holmium-doped fiber laser with vanadium carbide deposited on tapered fiber
TL;DR: In this paper, a vanadium carbide (V2C) was deposited onto a tapered fiber using the drop-casting technique and incorporated into a thulium/holmium doped fiber laser cavity for generating mode-locked outputs in the 2.0µm region.
Journal ArticleDOI
Q-Switched Yb-Doped Fiber Ring Laser with a Saturable Absorber Based on a Graphene Polyvinyl Alcohol Film
TL;DR: In this paper, a Q-switched ytterbium-doped fiber laser (YDFL) employing a thin graphene polyvinyl alcohol (PVA) film as a passive saturable absorber was proposed.
Journal ArticleDOI
Investigation of structural and optoelectronic properties of n-MoS2/p-Si sandwiched heterojunction photodetector
TL;DR: In this article, a polycrystalline MoS2 thin film is fabricated by radio frequency magnetron sputtering, which reveals two hexagonal structured peaks along the (100) and (110) planes, while energy-dispersive X-ray (EDX) spectroscopy confirms a non-stoichiometric Molybdenum disulphide film with a thickness of 300 nm.
Journal ArticleDOI
Passively mode-locked soliton fiber laser using a combination of saturable absorber and nonlinear polarization rotation technique
Nurul Shahrizan Shahabuddin,H. Mohamad,Mohd Adzir Mahdi,Zulfadzli Yusoff,Harith Ahmad,Sulaiman Wadi Harun +5 more
TL;DR: In this paper, an all-fiber passively mode-locked (ML) soliton fiber laser is demonstrated based on the combination of two ML mechanisms, single wall carbon nanotube saturable absorber, and nonlinear polarization rotation.
