Abstract
Over the past few decades, GaN-based LEDs have been widely used in solid-state lighting (SSL) due to their energy-saving and long-lifetime characteristics. However, the limited modulation bandwidth of conventional commercial LED chips limits their application in a high-speed visible light communication (VLC) system. Herein, this work designs vertical parallel micro-LED arrays with different array numbers to develop LED sources for communication and lighting. The as-prepared micro-LEDs in a 2 × 2 array reveal a high modulation bandwidth of ∼785 MHz at 6.67 kA/cm2. Meanwhile, the light output power is over 7 mW, which is more suitable for VLC in free space.
