Iraj Sadegh Amiri,Fatma Mohammed Aref Mahmoud Houssien,Ahmed Nabih Zaki Rashed,Abd El-Naser A. Mohammed +3 more
TL;DR: In this paper, the influence of thermal and spectral variations on various structures of avalanche photodiodes (APDs) have been deeply investigated and the characteristics and performance of Silicon (Si), Gallium Arsenide (GaAs), and Indium GalliumArsenide(InGaAs) APD structures have been evaluated under effects of different temperature degrees.
Journal ArticleDOI
Highly sensitive nonlinear photonic crystal fiber based sensor for chemical sensing applications
TL;DR: In this article, an extremely high sensitive and nonlinear chemical sensor based on photonic crystal fiber is presented with numerical investigation, in order to reduce fabrication complexity, the proposed chemical detector is designed with circular air holes.
Journal ArticleDOI
Optical communication transmission systems improvement based on chromatic and polarization Mode dispersion compensation simulation management
Iraj Sadegh Amiri,Ahmed Nabih Zaki Rashed,Hala M. Abd El Kader,Amr A. Al-Awamry,Ismail A. Abd El-Aziz,P. P. Yupapin,Gopinath Palai +6 more
TL;DR: In this article, a proposed compensation simulation model to handle not only chromatic dispersion but also polarization mode dispersion (PMD) simultaneously is presented. And the model is designed to analyze and simulate dispersion compensation technique which is based on deploying both fiber Bragg grating and emulator together till 250 km long of optical fiber.
