  "account": "A microchip the size of a grain of rice can generate a precise rainbow of light, a capability that could supercharge future 6G networks and enable precise timing for quantum technologies, according to Loughborough University physicists. The team collaborated with international researchers to demonstrate a system that produces multiple, precisely spaced light frequencies. These optical frequencies can be converted into millimeter waves, which have higher bandwidth potential for data transmission. Dr. Luke Peters of Loughborough's Emergent Photonics Research Centre noted that while the technology's full potential lies beyond communications, it could also benefit radar systems, spectroscopy, and astronomical instruments. Challenges remain, but this breakthrough addresses a major obstacle in generating many frequencies simultaneously, opening the door for real-world applications in the future.",
  "summary": "ScienceDaily reports: A microchip about the size of a grain of rice can generate a highly organized \"rainbow\" of light, a capability that could eventually support faster, higher-capacity 6G communications and extremely precise timing for quantum technologies. Physicists at Loughborough University, working with an international research team, demonstrated a system that produces a series of…",
