Influence of Asymmetric Gain Suppression on Relative Intensity Noise Properties of Multimode Semiconductor Lasers
Ahmed Bakry, Ahmed Alshahrie, Alaa Mahmoud +2
We introduce modeling and simulation of the noise properties associated with types of modal oscillations induced by scaling the asymmetric gain suppression (AGS) in multimode semic…
Stabilizing Multimode Hopping Oscillations and Reducing Associated Noise in Long Wavelength Laser Diode Using External Optical Feedback
Moustafa Ahmed, Ahmed Bakry, Ahmed Alshahrie +1
We report on converting the multimode hopping oscillation (MHO) in long-wavelength semiconductor laser into single-mode oscillation (SMO) by applying external optical feedback (OFB…
Transverse Coupled Cavity VCSEL: Making 100 GHz Bandwidth Achievable
Moustafa Ahmed, Ahmed Bakry, Ahmed Alshahrie +1
Enhancing the modulation bandwidth (MBW) of semiconductor lasers has been the challenge of research and technology to meet the need of high-speed photonic applications. In this pap…
Structure, Electrical and Optical Properties of ITO Thin Films and their Influence on Performance of CdS/CdTe Thin-Film Solar Cells
Moustafa Ahmed, Ahmed Bakry, Essam R. Shaaban +1
In terms of mixing graded TiO2 and SnO2 powders by solid-state reaction method, ITO was prepared. Using electron beam gun technology, ITO films with different thicknesses were prep…
