Micro-light-emitting diodes (µLEDs) hold significant promise for applications in displays and visible light communication (VLC). This study substantiates the viability of a wavelength division multiplexing (WDM)-VLC system using InGaN blue, green, and red µLED devices. The devices exhibited notable color stability and high modulation bandwidth due to the weakly polarized electric field in the blue and green semipolar devices and the stress-optimized structure in the red device. The aggregated data rate reached 11.14 Gbps. Moreover, the blue, green, and red InGaN µLEDs exhibited a wide color gamut, encompassing 119.4% of the NTSC and 89.2% of the Rec. 2020 standards, affirming the potential of blue, green, and red InGaN µLEDs for applications in full-color display and WDM-VLC systems.
微发光二极管（µLED）在显示器和可见光通信（VLC）应用中具有巨大潜力。本研究证实了使用氮化铟镓蓝色、绿色和红色µLED器件的波分复用（WDM）-VLC系统的可行性。由于蓝色和绿色半极性器件中的弱极化电场以及红色器件中的应力优化结构，这些器件表现出显著的颜色稳定性和高调制带宽。聚合数据速率达到11.14 Gbps。此外，蓝色、绿色和红色氮化铟镓µLED呈现出宽广的色域，涵盖了119.4%的NTSC和89.2%的Rec. 2020标准，证实了蓝色、绿色和红色氮化铟镓µLED在全彩显示和WDM-VLC系统应用中的潜力。
