Summary
Deep ultraviolet (DUV) micro-light-emitting diodes (LEDs) achieved record speeds for long-distance optical wireless communication. This technology enables over 1 Gb/s data rates at distances exceeding 100 meters.
Area of Science:
- Optoelectronics
- Optical Wireless Communications
Background:
- Optical wireless communication (OWC) offers high bandwidth potential.
- Deep ultraviolet (DUV) light-emitting diodes (LEDs) are emerging as promising transmitters for OWC.
Purpose of the Study:
- To demonstrate the feasibility of DUV micro-LEDs for long-distance OWC.
- To achieve high data rates over extended ranges using DUV micro-LEDs.
Main Methods:
- Utilized a single 285 nm-emitting micro-LED as the transmitter.
- Conducted experiments to measure data rates at various distances.
Main Results:
- Achieved >6.5 Gb/s at 10 m and 4 Gb/s at 60 m.
- Demonstrated >1 Gb/s data rates at a distance of 116 m.
- These represent the highest data rates reported for DUV micro-LEDs at these distances.
Conclusions:
- DUV micro-LEDs are capable of high-speed, long-distance OWC.
- This technology enables Gb/s communication beyond 100 m, a first for micro-LED transmitters.
