Beam-steering-based optical wireless technologies are being widely investigated due to the capability of providing high-speed wireless connectivity in indoor applications. However, high-speed indoor optical wireless systems are traditionally realized with discrete bulky components, significantly limiting their practical applications. In this Letter, we demonstrate an infrared optical wireless communication system employing a miniaturized silicon integrated photonic circuit for beam steering for the first time. Experimental results show that up to 12.5 Gb/s optical wireless communication can be achieved with error-free performance over a free-space range of 140 cm, and limited mobility of users can be realized. The experimental results of this Letter open the way for realizing integrated high-speed optical wireless communications.
基于波束转向的光无线技术由于能够在室内应用中提供高速无线连接而受到广泛研究。然而，传统上高速室内光无线系统是通过离散的大型组件实现的，这极大地限制了它们的实际应用。在本信中，我们首次展示了一种采用小型化硅基集成光子电路进行波束转向的红外光无线通信系统。实验结果表明，在 140cm 的自由空间范围内可以实现无误码的 12.5Gb/s 光无线通信，并且可以实现用户的有限移动性。本信的实验结果为实现集成高速光无线通信开辟了道路。
