micro-LEDs

GaN-based light emitting diodes (LEDs) are the ideal light sources for visible light communication (VLC). However, both the low modulation bandwidth (MB) and unstable lighting output power (LOP) of LEDs at high current density that restrict the further development of VLC. In this work, micro-LEDs (μLEDs) with embedded N electrodes have been proposed, possessing high MB and remarkable stability.
