Abstract
LED-to-LED visible light communication (VLC), which uses LEDs not only for the transmitter but also for the receiver, is being studied as an efficient optical wireless communication technology that uses LED lighting infrastructure. In this paper, we investigate microLED-to-LED VLC, which uses microLEDs as both the transmitter and receiver. In particular, we conducted a study to improve the performance of microLED-to-microLED VLC. For this, we measured the performance depending on the transmitter and receiver LED color combination. In addition, the effects of zero bias and reverse bias at the receiver LED were investigated. We also investigated the improvement in the reverse bias when applying a transimpedance amplifier to the receiver LED. Finally, we experimentally demonstrated a data rate of 360 kbps in the microLED-to-microLED VLC.
LED 对 LED 可见光通信（VLC）不仅将 LED 用作发射器，还将其用作接收器，作为一种利用 LED 照明基础设施的高效光无线通信技术，目前正在对其进行研究。在本文中，我们研究了同时使用微型 LED 作为发射器和接收器的微型 LED 对 LED 可见光通信（VLC）。我们特别研究了如何提高 microLED 对 microLED VLC 的性能。为此，我们测量了发射器和接收器 LED 颜色组合的性能。此外，我们还研究了接收器 LED 的零偏压和反向偏压的影响。我们还研究了在接收器 LED 上应用跨阻放大器对反向偏置的改善。最后，我们通过实验演示了微型 LED 到微型 LED VLC 的 360 kbps 数据传输速率。
