Visible Light Communications (VLC) can provide both illumination and communications and offers a means to alleviate the predicted spectrum crunch for radio-frequency wireless communications. In this paper, we report a laser diode based white-light communications link that operates over a wide area and supports high data rates. The proposed system is a four-colour multiplexed high-speed VLC system that uses a microelectromechanical system (MEMS) mirror-based beam-steering. The system operates at record data-rates of more than 35 Gb/s (Bit Error Rate(BER) < 3.8 × 10) with a coverage area of 39 m at a link distance of 4 m. To the best of our knowledge this is the fastest VLC demonstration reported thus far. The paper also addresses issues of eye-safety, showing data rates of more than 10 Gb/s are feasible.
可见光通信（VLC）既能提供照明又能实现通信，为缓解预计的射频无线通信频谱短缺问题提供了一种手段。在本文中，我们报告了一种基于激光二极管的白光通信链路，该链路可在大面积区域运行并支持高数据速率。所提出的系统是一种四色复用高速VLC系统，它采用基于微机电系统（MEMS）镜的光束转向技术。该系统在链路距离为4米时，以超过35 Gb/s的创纪录数据速率（误码率（BER）< 3.8×10）运行，覆盖面积达39平方米。据我们所知，这是迄今为止报道的最快的VLC演示。本文还讨论了眼睛安全问题，表明超过10 Gb/s的数据速率是可行的。
