Journal ArticleDOI
Optical frequency comb generation based on chirping of Mach-Zehnder Modulators
Jassim K. Hmood,Jassim K. Hmood,Siamak Dawazdah Emami,Kamarul Ariffin Noordin,Harith Ahmad,Sulaiman Wadi Harun,Hossam M. H. Shalaby +6 more
TL;DR: In this paper, a new approach for the generation of an optical frequency comb, based on chirping of modulators, is proposed and numerically demonstrated, which includes two cascaded Mach-Zehnder Modulators (MZMs), a sinusoidal wave oscillator, and an electrical time delay.
Journal ArticleDOI
Performance analysis of an all-optical OFDM system in presence of non-linear phase noise
Jassim K. Hmood,Sulaiman Wadi Harun,Siamak Dawazdah Emami,Amin Khodaei,Kamarul Ariffin Noordin,Harith Ahmad,Hossam M. H. Shalaby +6 more
TL;DR: An analytical model for estimating the phase noise due to self- phase modulation, cross-phase modulation, and four-wave mixing in an all-optical OFDM system is presented and it is shown that the phase variance due to FWM is dominant over those induced by either SPM or XPM.
Journal ArticleDOI
Q-switched erbium-doped fiber laser based on nanodiamond saturable absorber
TL;DR: In this paper, a solid nanocomposite film is prepared by the drop-casting method where nanodiamond particles are embedded into polyvinylidene fluoride-trifluoroethylene (PVDF-TRFE).
Journal ArticleDOI
PAPR reduction in all-optical OFDM based on time interleaving odd and even subcarriers
TL;DR: In this paper, a new all-optical approach for reducing peak-to-average power ratio (PAPR) in orthogonal frequency division multiplexing (AO-OFDM) system based on time interleaving odd and even subcarriers is proposed and analytically modeled.
Journal ArticleDOI
Mitigation of phase noise in all-optical OFDM systems based on minimizing interaction time between subcarriers
Jassim K. Hmood,Kamarul Ariffin Noordin,Sulaiman Wadi Harun,Hossam M. H. Shalaby,Hossam M. H. Shalaby +4 more
TL;DR: The results reveal that the nonlinear phase noise (NPN) due to fiber nonlinearity is significantly mitigated when the time delay between the odd and even subcarriers is equal to half the symbol period.
