Semiconductors are pervasive in consumer electronics and optoelectronics, and the related optical devices are deemed disruptive that Nobel Prize in Physics in 2014 was awarded to the inventors of blue light-emitting diodes (LEDs), which “has enabled bright and energy-saving white light sources”. While AlInGaN-based lasers and LEDs, and silicon-based photodetectors are currently matured, unconventional usage based on the materials has demonstrated their further potential, including solar-hydrogen generation, indoor-horticulture, and high-speed communication.

Ahmad Ali Al-Jabr

Ph.D., Electrical and Computer Engineering

LED Laser Diodes

Ahmad Al-Jabr was a Ph.D. researcher at Photonics Laboratory under the supervision of Professor Boon Ooi at King Abdullah University of Science and Technology (KAUST). His Ph.D. work was focused on studying plasmonics and related physical phenomenon in highly-doped semiconductors and metal structures. He also applied his expertise in finite difference time domain (FDTD) theoretical simulation in understanding plasmonics effects in the structures, as well as designing practical plasmonic devices for eventual applications in photonic integrated circuits (PIC). Ahmad received his M.Sc. and B.Sc
