The Main Role of Thermal Annealing in Controlling the Structural and Optical Properties of ITO Thin Film Layer
Moustafa Ahmed, Ahmed Bakry, Ammar Qasem +1
Here we report on studying the electronic and optical material properties of the technologically-relevant material indium tin oxide (ITO) as a function of thermal annealing. In thi…
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
