Numerical modeling of intensity and phase noise in semiconductor lasers
TL;DR: In this paper, a self-consistent numerical approach is demonstrated to analyze intensity and phase noise in semiconductor lasers, taking into account the intrinsic fluctuations of the photon number, carrier number, and phase.
Journal ArticleDOI
Physical, optical and gamma radiation shielding competence of newly boro-tellurite based glasses: TeO2–B2O3–ZnO–Li2O3–Bi2O3
M.I. Sayyed,M.I. Sayyed,Yas Al-Hadeethi,Maha M. AlShammari,Moustafa Ahmed,Saleh H. Al-Heniti,Y.S. Rammah +6 more
TL;DR: In this article, a traditional melt quenching method was utilized to synthesize glasses with a nominal chemical composition (80-x)TeO2-xB2O3-5ZnO-5Li 2O3−10Bi2O-3: 30≤ x−≤ ǫ −80 −mol%).
Journal ArticleDOI
Influence of instantaneous mode competition on the dynamics of semiconductor lasers
Moustafa Ahmed,Minoru Yamada +1 more
TL;DR: In this article, a comprehensive theoretical investigation of the influence of instantaneous mode-competition phenomena on the dynamics of semiconductor laser systems is presented, based on numerical simulations of the multimode rate equations superposed by Langevin noise sources that account for the intrinsic fluctuations associated with the spontaneous emission.
Journal ArticleDOI
An improved analysis of semiconductor laser dynamics under strong optical feedback
TL;DR: In this article, an improved theoretical model was proposed to analyze the dynamics and operation of semiconductor laser under optical feedback (OFB) for arbitrary strength of OFB ranging from weak to very strong.
Journal ArticleDOI
Field fluctuations and spectral line shape in semiconductor lasers subjected to optical feedback
Moustafa Ahmed,Minoru Yamada +1 more
TL;DR: In this article, the spectral line shape and the associated spectra of the relative intensity noise (RIN) and frequency noise (FN) in semiconductor lasers were investigated based on a generalized simulation model that treated the OFB as a multiple-roundtrip time delay of the lasing field in the external cavity.
