摘要：

The advancement demands of high-speed wireless data link ask for higher requirements on visible light communication (VLC), where wide coverage stands as a critical criterion. Here, we present the design and implementation of a transmitter structure capable of emitting a high -power wide -coverage white light laser. This laser source exhibits excellent stability, with an irradiation range extending to a half -angle of 20 degrees. Its high brightness satisfies the needs of indoor illumination while maintaining excellent communication performance. Utilizing bit -loading discrete multi -tone modulation, a peak data transmission rate of 3.24 Gbps has been achieved, spanning 1 to 5 m. Remarkably, the data rates exceed 2.5 Gbps within a 40 degrees range at a distance of 5 m, enabling a long-distance, wide coverage, high-speed VLC link for future mobile network applications.
