Visible light communications (VLC) is considered a potential key technology for 6G. However, the performance of transceiver devices of VLC determines the upper limit of system. InGaN/GaN based light-emitting diodes (LEDs) have widely been used as the transmitter. In this paper, a VLC transceiver system is designed on the basis of InGaN/GaN blue light laser diode (LD). The transmitted signals are designed based on the 5G new radio (NR) physical layer protocol. The experiment verifies the feasibility of 256 quadrature amplitude modulation (QAM) and the blue LD-based VLC system can achieve up to 14Gbit/s system sum rate when adopting 5G NR protocol, which contributes to the application of VLC in 6G systems.
