TL;DR: In this article, a ring cavity passively harmonic mode-locked fiber laser using a newly developed thuliumbismuth co-doped fiber (TBF) as a gain medium in conjunction with a carbon nanotube (CNT)-based saturable absorber was reported.
Journal ArticleDOI
Proposal and performance evaluation of an efficient RZ-DQPSK modulation scheme in all-optical OFDM transmission systems
S. E. Mirnia,A. Zarei,Siamak Dawazdah Emami,Sulaiman Wadi Harun,Hamzah Arof,Harith Ahmad,Hossam M. H. Shalaby +6 more
TL;DR: The results reveal that the proposed DQPSK modulation scheme outperforms the traditional one in all four aforementioned performance measures, yet the spectral efficiency is almost preserved.
Journal ArticleDOI
Wideband and flat gain series erbium doped fiber amplifier using hybrid active fiber with backward pumping distribution technique
Alabbas A. Al-Azzawi,Aya A. Almukhtar,Belal Ahmed Hamida,Subha R. Das,Anirban Dhar,Mukul Chandra Paul,Hijaz Ahmad,Sulaiman Wadi Harun,Sulaiman Wadi Harun +8 more
TL;DR: In this article, a wideband and flat gain erbium-doped fiber amplifier (EDFA) was proposed by employing a recently fabricated hafnia-bismuth-erbium doped fiber (HB-EDF) and zirconia-binarium-edf (Zr-EDF) as a hybrid active fiber.
Journal ArticleDOI
Environment-independent liquid level sensing based on fiber-optic displacement sensors
TL;DR: In this article, a new fiber-optic liquid-level sensor (LLS) for continuous monitoring of the liquid level is proposed using a fiber-Optic displacement sensor (FODS).
Journal ArticleDOI
Excitation of core modes through side coupling to multimode optical fiber by hydrothermal growth of ZnO nanorods for wide angle optical reception
TL;DR: In this article, side coupling to core modes through zinc oxide (ZnO) nanorods grown around the fiber was demonstrated by using wet etching of the cladding region followed by hydrothermal gr...
