Tiny Optical Crystal Paves Way for Faster 6G Communications

Researchers from Loughborough University and their international partners have developed a rice-grain-sized microchip capable of generating a stable spectrum of light frequencies—known as a microcomb—and converting them into an array of high-frequency electromagnetic signals, specifically millimeter waves. While the chip itself is miniature, the system highlights a fundamental tension in next-generation hardware: the gap between a successful com…
