In this paper, we fabricated a 3×3 violet series-biased micro-LED array with high-output optical power and applied it in high-speed and long-distance visible light communication. By employing the orthogonal frequency division multiplexing modulation scheme, distance adaptive pre-equalization, and a bit-loading algorithm, record data rates of 10.23 Gbps, 10.10 Gbps, and 9.51 Gbps were achieved at 0.2 m, 1 m, and 10 m, respectively, below the forward error correction limit of 3.8×10. To the best of our knowledge, these are the highest data rates achieved by violet micro-LEDs in free space and the first communication demonstration beyond 9.5 Gbps at 10 m using micro-LEDs.
在本文中，我们制作了一个 3×3 的紫光序列偏置微 LED 阵列，具有高输出光功率，并将其应用于高速长距离可见光通信。通过采用正交频分复用调制方案、距离自适应预均衡和位加载算法，在 0.2 m、1 m 和 10 m 处分别实现了 10.23 Gbps、10.10 Gbps 和 9.51 Gbps 的记录数据速率，均低于 3.8×10 的前向纠错限。据我们所知，这是紫光微 LED 在自由空间中实现的最高数据速率，也是首次使用微 LED 在 10 m 处实现超过 9.5 Gbps 的通信演示。
