Laser-Based Wireless System Reaches 360 Gbps While Cutting Energy Use in Half

As demand for bandwidth-intensive applications continues to grow, researchers from the University of Cambridge are exploring alternatives to traditional radio-frequency wireless networks. One promising development comes from a team that has demonstrated a chip-scale optical wireless communication system capable of delivering more than 360 Gbps using near-infrared laser light instead of radio waves. The system is built around a compact 5×5 array of vertical-cavity surface-emitting lasers (VCSELs)
