100m Free-Space Over 10Gbps Visible Light Laser Communication Using Gallium-nitride Blue LD and Huffman-coded Dyadic Probabilistic Shaping

Abstract

In this experiment, we achieved over 10Gbps transmission rate in a 100m free-space visible light laser communication system. Huffman-coded QAM provides probabilistic shaping effects and improves the system's working range and robustness against turbulence.
