KAUST Professor Boon Ooi, Nobel laureate Shuji Nakamura from UCSB, and KACST researchers are collaborating on laser-based solid-state lighting (SSL) through a 2014 tripartite agreement. Their research focuses on SSL, which has the potential to be even more energy-efficient than existing LED lighting by using semiconductor lasers. Nakamura, who won the Nobel Prize in Physics in 2014 for developing blue LEDs, spoke at KAUST about the potential of SSL to improve energy efficiency further. Why it matters: This collaboration aims to advance energy-efficient lighting technologies, leveraging Nobel-winning expertise to develop solutions that could significantly reduce global energy consumption.
KAUST Professor Boon Ooi, Nobel laureate Shuji Nakamura, and colleagues are collaborating on laser-based solid state lighting (SSL) and visible light communications (VLC). The team is using gallium nitride (GaN) to develop high-performance semiconductor laser devices, leveraging nanofabrication techniques at KAUST. They demonstrated that their laser-based VLC system is over 20 times faster than LED-based Li-Fi systems. Why it matters: This research could enable faster, more energy-efficient data transmission using visible light, with potential applications in both terrestrial and underwater communication.
KAUST held an open day on December 3, 2015, to celebrate the International Year of Light. The event showcased technological developments in light research, especially photonics and LED-based technologies. Exhibits and demonstrations were provided by researchers from KAUST's CEMSE and PSE divisions, under the direction of Professor Boon Ooi. Why it matters: The event promoted understanding of achievements in light research and its applications in various sectors like communications, medicine, and energy.
KAUST startup Quantum Solutions manufactures quantum dots, semiconducting nanoparticles that emit light with controllable energy. These dots are being explored for applications including displays, photodetectors, and solar cells. Quantum dots can enhance the efficiency of silicon solar panels by absorbing infrared light. Why it matters: This highlights the potential of KAUST-incubated startups to contribute to advanced materials science and renewable energy technologies in the region.
KAUST and KACST researchers have developed a nanoPE nanoplastic that improves LED streetlight energy efficiency by enhancing thermal radiation emission and reducing LED temperature. The nanoPE coating allows infrared light to pass through while reflecting visible light, optimizing illumination. Simulations suggest that adopting this technology in the US could reduce carbon dioxide emissions by over one million metric tons. Why it matters: This innovation offers a sustainable lighting solution with significant potential for reducing energy consumption and carbon emissions in Saudi Arabia and globally.
