We study the trade-off between energy harvesting and data communication for a two-meter wireless gallium-arsenide vertical-cavity surface-emitting laser and photovoltaic link. The use of orthogonal frequency-division multiplexing with adaptive bit and power loading results in a peak data rate of 1041 Mb/s at a bit-error ratio (BER) of $2.2\times 10^{-3}$ under short-circuit conditions. The receiver is shown to provide power harvesting with an efficiency of 41.7% under the irradiance of 0.3 W/cm² and simultaneous data communication with a rate of 784 Mb/s at a BER of $2.8\times 10^{-3}$ . The experimental system is envisioned to become a paradigm for next-generation wireless backhaul communications and Internet-of-Things applications.

用于 1 Gb/s GaAs VCSEL 和光伏链路的同步无线数据和电力传输

我们研究了两米无线砷化镓垂直腔面发射激光器和光伏链路的能量收集和数据通信之间的权衡。使用具有自适应比特和功率负载的正交频分复用导致峰值数据速率为 1041 Mb/s，误码率 (BER) 为 $2.2\times 10^{-3}$ 在短路条件下。该接收器在 0.3 W/cm ²的辐照度下以 41.7% 的效率提供功率收集，同时以 784 Mb/s 的速率进行数据通信，BER 为 $2.8\乘以 10^{-3}$ . 该实验系统有望成为下一代无线回程通信和物联网应用的典范。
