About Omar Alkhazragi Omar Alkhazragi Ph.D. Student, Electrical and Computer Engineering optoelectronics optical wireless communicaitons Introduction Omar Alkhazragi received the degree of Bachelor of Science in Electrical Engineering in 2018 from King Fahd University of Petroleum and Minerals, Dhahran, Saudi Arabia, and a master’s degree in electrophysics in 2019 from King Abdullah University of Science and Technology (KAUST), Thuwal, Saudi Arabia. He is now an electrophysics Ph.D. student in the Photonics Laboratory at KAUST. The primary focus of his research is on optoelectronic devices fabrication and applications, including optical and quantum communication. Research Interests Photonics and optoelectronics Semiconductor Events Presented Events Oct 8 - Oct 14, 2023 Low-Coherence Surface-Emitting Lasers for Optical Wireless Communication and Low-Speckle Illumination Omar Alkhazragi, Ph.D. Student, Electrical and Computer Engineering Oct 8, 10:00 - 11:30 B2 L5 R5220 Highly coherent light, although beneficial in specific applications, suffers from the formation of speckles, resulting in poor imaging, lighting, and projection/display quality. Moreover, the long coherence length limits the resolution in interference based sensing. The aim of this dissertation is to design low-coherence surface-emitting lasers to push simultaneous illumination and optical wireless communication (OWC) toward reliable implementation with higher speeds.
