Nanocrystals that generate white light could help combine lighting and communications systems into one.
"A technique developed by scientists at KAUST has made more controlled fabrication of optoelectronic devices produced from a hybrid of organic and inorganic materials possible."
Adding a gas enhances the processing of hybrid organic-inorganic materials for improved solar cells.
Ahmad Ali Al-Jabr has successfully defended his PhD thesis "Development of Strain-Induced Quantum Well Intermixing Technique on InGaP/InAlGaP Laser Structures and Demonstration of First Orange Laser Diode."
"In this bandwidth hungry era, there will be a continuous push by consumers for VLC systems with higher bitrates," Ooi said. "We believe that white light generated by semiconductor lasers will one day replace the LED white light bulb for energy-efficient lighting."
Prof. Boon Ooi, Chao Zhao, Chao Shen and Hassan Oubei at CLEO:2016 in San Jose, USA.
KAUST has developed a quantum well intermixing technique to blue-shift indium gallium phosphide (InGaP) quantum well bandgaps to give 628nm red, 602nm orange and 585nm yellow electroluminescence.
Chao Shen is rewarded with Incubic/Milton Chang travel grant for CLEO:2016.
Yellow and orange sources (LED & LD) result from the controlled annealing of phosphide material systems with a dielectric cap.
KAUST is starting to play a more domestic role by opening its excellent facilities to researchers from other Saudi Arabian research institutes.
In this talk, we discuss our recent investigations on laser-diodes and the related light-emitting diodes material-structures for lighting, and data communications.
Semiconductor light-emitting diodes fabricated on a metal substrate are less prone to overheating.
The Computer, Electrical and Mathematical Science and Engineering Division invited the KAUST community to join the celebration for the International Year of Light 2015.
The International Year of Light (IYL) Open Day event took place at KAUST on December 3, 2015.
Congratulation to Hassan Oubei on his recent paper being highlighted in Nature Photonics- 4.8 Gbit/s 16-QAM-OFDM transmission based on compact 450-nm laser for underwater wireless optical communication.
