Micro-LED Based Double-Sided Emission Display and Cross-Medium Communication

GaN micro-LEDs have been spotlighted as promising candidates for high-speed optical communication, which may become important components in 6G communication blueprint. To achieve a superior network covering sea, land and air we demonstrated cross-medium based on an 80 $\mu$ m double-sided emission micro-LED array. The high enough light output power radiated from both sides of the green enabled interference-free signal transmission different media. Data rates 1.55 Gbps over 3 free-space link 1.11 3.4 underwater could be achieved simultaneously. Furthermore, parallel-connected were utilized to demonstrate feasibility pattern display expected longer distances media such channels.
