Abstract

Optical wireless data transmission is an emerging complementary technology compared to the radio frequency transmission. Due to the characteristics of optical radiation, optical wireless transmission has high-speed data transmission, unlimited bandwidth, high security and immune to signal interference. Despite from most self-alignment optical wireless systems such as MEMS, optical phased array (OPA) has a large advantage on the entire system size, low power consumption and high speed operation. The manufactured OPA has 16 channels, achieving ±22.7° beam steering angle. Radiator's output beam has a beam divergence angle of 4° and 6° for each horizontal and vertical direction. By using the OPA, we have demonstrated a 5Gbps data transmission in free space. By phase tuning, data transmission can shift from center positioned photodetector to another photodetector at fully steered beam position. The extinction ratio of the transmission eye-diagram was over than 7dB. These results show that OPA is a promising technology for high-speed optical wireless communication with self-alignment function.

基于硅光相控阵的波束控制高速无线通信

光无线数据传输是相对于射频传输的一种新兴的补充技术。由于光辐射的特性，光无线传输具有高速数据传输、无限带宽、高安全性和不受信号干扰等特点。与大多数自对准光学无线系统(如MEMS)相比，光学相控阵(OPA)在整个系统尺寸、低功耗和高速运行方面具有很大的优势。制造的OPA有16个通道，实现±22.7°波束转向角。散热器的输出光束在水平和垂直方向上的发散角分别为4°和6°。通过使用OPA，我们已经演示了在空闲空间中5Gbps的数据传输。通过相位调谐，数据传输可以从中心位置的光电探测器转移到光束完全导向位置的另一个光电探测器。透射眼图消光比大于7dB。结果表明，OPA是一种具有自对准功能的高速无线光通信技术。
