摘要：

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 x 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/cm(2) and simultaneous data communication with a rate of 784 Mb/s at a BER of 2.8 x 10(-3). The experimental system is envisioned to become a paradigm for next-generation wireless backhaul communications and Internet-of-Things applications.
