ABSTRACT
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°. 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 3.24â
Gbps has been achieved, spanning 1 to 5â
m. Remarkably, the data rates exceed 2.5â
Gbps within a 40° range at a distance of 5â
m, enabling a long-distance, wide coverage, high-speed VLC link for future mobile network applications.
