First laser radio paves the way for ultra-fast WiFi
Researchers at the Harvard School of Engineering and Applied Sciences have developed a method to wirelessly transmit radio frequency via a semiconductor laser. The breakthrough, published in Proceedings of the National Academy of Sciences, is a marked advancement on conventional lasers, which can only emit a single frequency of light. The researcher's development can use lasers to emit microwaves, modulate them and receive external radio frequency signals, which opens up the possibility for "ultra-high-speed WiFi."
