Dr. Nasir Alfaraj is a KAUST Ibn Rushd Fellow at the Edward S. Rogers Sr. Department of Electrical and Computer Engineering, University of Toronto, Ontario, Canada. He received his Ph.D. in Electrical Engineering from King Abdullah University of Science and Technology (KAUST) in Thuwal, Saudi Arabia, in 2019. Prior to his doctoral studies, he earned his B.Sc. (2013) from Western Michigan University, Kalamazoo, MI, USA, and his M.Sc. (2015) from KAUST. Dr. Alfaraj is currently a Research Associate with the Helmy Group, and his research interests encompass the growth, fabrication, and characterization of CMOS-compatible semiconductor nanostructures and devices for nanophotonic applications, utilizing hybrid metallic architectures. He is an IEEE Senior Member.

Nasir's research investigated the design and clean-environment fabrication of solid-state and optoelectronic devices, including field-effect transistors and light-emitting diodes. His research expertise spans the areas of flexible electronics; optoelectronic device growth, fabrication, and characterization; and free-space optical communication. His research interests included Growth, fabrication, and characterization of group-III-nitride-based nanostructures for next-generation devices, Semiconductor physics and Quantum mechanics.

Yue Wang is a Ph.D. candidate at the Photonics Laboratory at King Abdullah University of Science and Technology (KAUST), under the mentorship of Prof. Boon S. Ooi. She earned her B.Eng. in Electronic Science and Technology from the University of Electronic Science and Technology of China (UESTC) in 2020. She received her master's degree in Electrical Engineering from KAUST in 2021.

Yue Wang's research focuses on semiconductor optoelectronics, high-speed color-converting luminescent devices, and optical wireless communication. She specializes in characterizing color-converting materials, designing and fabricating luminescent optoelectronic devices, and developing optical wireless communication systems.

Yue Wang has explored emerging luminescent materials such as perovskites, metal-organic frameworks (MOFs), and organic fluorophores, enabling Gb/s visible light communication and wavelength-division multiplexing with enhanced channel capacity. To relieve the stringent requirements of pointing, acquisition, and tracking in underwater optical wireless communication channels, she employed scintillating fibers and luminescent solar concentrators for wide field-of-view, high-speed photodetection. Her work also extends to optical amplification, where she has developed a high-gain visible-light amplifier based on perovskite quantum dots, potentially addressing the optical loss during long-distance optical data transmission.

Hang Lu is a final-year Ph.D. student in Electrical and Computer Engineering at King Abdullah University of Science and Technology (KAUST), working in the Photonics Laboratory under the supervision of Prof. Boon S. Ooi. Hang has published in Light: Science & Applications, npj Nanophotonics, and APL Photonics, with her work featured as a cover article in the IEEE Journal of Selected Topics in Quantum Electronics. She also has experience in designing augmented-reality (AR) display systems and is broadly interested in advanced photonic integration and device–application co-design.

Hang's research focuses on engineering optoelectronic devices and photonic integration circuits for applications in optical communication, illumination, and hardware security. She has hands-on experience in optical design and modeling, nanofabrication, and experimental device prototyping, and has led the development of integrated optoelectronic devices and chips for secure and scalable photonic applications.
