First Demonstration of Multi-user QAM-OFDMA Visible Light Communication System Based on a 75-μm Single Layer Quantum Dot Blue Micro-LED
2020 Conference on Lasers and Electro-Optics (CLEO), 2020•ieeexplore.ieee.org
… We present, for the first time, a two-user OFDMA VLC system based on the packaged QD
micro-LED, which realizes 2.5 Gbaud error-free transmission of QAM-OFDMA signals for the
user occupying lower frequency band and 1.6 Gbaud transmission for the high-frequency
user with a BER of 3.6×10-3 below the forward error correction (FEC) threshold over 3-m
transmission distance. … In summary, this work proposed and experimentally demonstrated
a two-user 3-m high-speed QAM-OFDMA VLC system based on a packaged ultra-high 1.03 …

We demonstrate a 3-meter 2.5-Gbaud QAM-OFDMA visible light communication (VLC) system affording two users by implementing a 75-μm single layer quantum dot (QD) blue micro-LED with achieved extremely high packaging modulation bandwidth at 1.03 GHz.
