Current 5G wireless networks work like highways through which information moves at high speeds, allowing for fast communication.
Scientists have claimed that their laser-powered engines may soon support “intelligent” 6G networks. The team demonstrated a laser-driven engine made from an easy-to-manufacture ceramic material that uses white light to move information over large distances.
This is a key step toward developing next-generation, AI-enabled 6G wireless networks.
While conventional LED‑based visible light communication (VLC) systems typically operate over only a few meters, the novel photonic engine can move data over 1.2 kilometers.
Direct experimental evidence supporting 6G communications
Described in a study publishing May 22 in the Cell Press journal Matter, the findings offer direct experimental evidence supporting 6G communications technology.
The photonic engine powered by lasers can transfer large amounts of data over long distances by emitting high-quality white light–qualities that place it at the forefront of laser lighting technologies.
“This is really a record with attractive performance beyond the traditional technology,” says Zhiguo Xia of South China University of Technology in Guangzhou, China.
“This work also provides compelling experimental support for the application of laser lighting in scenarios such as drone logistics and low‑altitude air travel,” said Xia.
Engine mainly emits light in the yellow region
Researchers noted that the engine mainly emits light in the yellow region (500–650 nm) and lacks red components, limiting its use in applications requiring a very high color rendering index–a measure of an object’s true color compared to natural sunlight. It also operates at far below fiber optic speeds. To further develop the engine, the team plans to investigate light-emitting materials with shorter fluorescence lifetimes and tunable emission bandwidths, which can further speed up data rates. They also plan to integrate the laser system with radio-frequency systems to ensure that service continues during bad weather.
“AI‑driven link adaptation can dynamically adjust data rate and optical power, ultimately supporting a future 6G network that is space‑air‑ground integrated, fully covered, and highly reliable,” said Xia.
High-speed photodetectors into compact devices
Scientists revealed that previously researchers have faced barriers to developing 6G technology, including the need for ultra-dense base stations with high energy and infrastructure costs, as well as challenges in combining high-performance lighting materials and high-speed photodetectors into compact devices that can be mass-produced at low cost.
To address these challenges, Xia’s team developed the photonic engine powered by lasers that can transfer large amounts of data over long distances by emitting high-quality white light–qualities that place it at the forefront of laser lighting technologies.
Current 5G wireless networks work like highways through which information moves at high speeds, allowing for fast communication. 6G networks built into future smartphones and other objects such as streetlamps would not only allow information to move through networks an order of magnitude faster–they would be able to “see,” “hear,” and “think,” detecting people and objects and their subtle movements. Since 6G networks would incorporate data from satellites fixed low in Earth’s orbit, they could even provide high-speed coverage in tough-to-reach regions such as deserts, oceans, and mountains.
“We developed a facile protocol for fabricating wafer-scale, quasi-transparent ceramics via a stepped glass crystallization process in aluminosilicate glasses of Lu2O3–CaO–MgO–Al2O3–SiO2,” said researchers in the study.
“By combining experiments and computational modeling, we demonstrated that the densified crystallization originates from the tailored design of crystallization energy barriers and the activation of ion migration channels within the amorphous LCMAS:Ce glass network.”
