Researchers at the University of Surrey and the University of Cambridge have found that LED bulbs using metal halide peroxides can facilitate fast data transmission. This breakthrough in LED technology will revolutionize home and office networks, greatly improving the speed and efficiency of data communication.
The use of metal halide peritectic LED light bulbs can greatly speed up data transmission in homes and offices, marking a major advance in communications technology, a study has shown.
With light-emitting diode (LED) bulbs, fast data transmission can be achieved in homes and offices, complementing existing communication technologies and networks.
The academic community is rapidly perfecting the new Internet technologies of the future, and LED-based communication links are expected to be widely used in a number of emerging services and scenarios, including light fidelity (Li-Fi), underwater communications, medium – and high-speed photonic interconnects, and various “Internet of Things” (IoT) devices.
A new study led by the University of Surrey and the University of Cambridge has investigated how metal halide peritectic crystals can be used to release a high-speed photon source. These semiconductors are being studied together with leds because of their excellent photoelectric properties and low-cost processing methods.
Dr Wei Zhang, Associate Professor at the University of Surrey’s Institute of Advanced Technology and lead corresponding author of the study, said: “Hundreds of millions of iot connected devices have the potential to bring huge value to industry and the global economy. In this market, cost and compatibility often take precedence over data transfer speed, and scientists are looking for other ways to reduce power consumption per bit and increase compactness while working to improve data connection speeds.”
“In our research, we have made a huge leap forward in showing how metal halide peroxides can provide a cost-effective and powerful solution to manufacture leds that have great potential to increase bandwidth to the gigahertz class.” The insights gained from this research will undoubtedly shape the future of data communications. In addition, our research will accelerate the development of high-speed peritectic photodetectors and continuous-wave pumped peritectic lasers, thus opening up new avenues for the advancement of optoelectronic technology.”
Co-first author Hao Wang, a PhD student at the University of Cambridge, said: “Our research has for the first time elucidated the mechanism behind the realization of high-speed peritectic light-emitting diodes, which represents an important step towards enabling the next generation of peritectic light sources for data communication. The ability to process peritectic emitters in solution on silicon substrates also paves the way for their integration with microelectronics platforms, providing new opportunities for seamless integration and advancement in the field of data communications.”
The research, published in the journal Nature Photonics, is a collaborative project with support from more than 10 laboratories and research institutions including Oxford, Cambridge, Bath, Warwick, UCL, EMPA and UESTC.
