Scientists unveiled a chip smaller than a millimeter for optical wireless data. It uses a 25-laser array to transmit at 362.7 gigabits per second. The system consumes roughly half the energy of conventional Wi-Fi. It shapes light into a structured grid to prevent interference and enable multiuser capability. This technology is designed to complement existing networks in high-traffic indoor spaces. Scientists have just unveiled a wireless breakthrough that could make today’s internet feel like a dial-up modem. Researchers have developed a chip smaller than a millimeter that uses an array of 25 tiny infrared lasers to transmit data at a blistering 362.7 gigabits per…
