This optical wireless chip introduces a new way to manage rising indoor connectivity demands by transmitting data through infrared light instead of radio waves. In a study reported in Advanced Photonics Nexus, researchers developed a compact system built around a 5 × 5 array of vertical-cavity surface-emitting lasers, or VCSELs, enabling multiple high-speed data streams to operate simultaneously.
By directing light into structured beams, the system reduces interference in dense indoor environments while delivering significantly higher data capacity. It also improves energy efficiency, using less power per bit than traditional Wi-Fi, making it suitable for data-heavy applications like streaming and smart devices.
This technology creates opportunities for telecom providers and hardware companies to enhance indoor networks, reduce congestion, and lower energy costs across offices, hospitals, and data-driven environments.
