MOST: New Record on Ultrafast Green Micro-LED Array

Published: Feb 17,2022

“Ultrafast optical wireless data streaming for transmitting a high-definition video signal within one second with directly using the smart display made by RGB micro-LEDs” will come true soon. Under the continued support by the Ministry of Science and Technology (MOST) in Taiwan, Professor Gong-Ru Lin, Professor Hao-Chung Kuo, and Dr. Chih-Hsien Cheng collaborate to demonstrate the worldwide new record on “Beyond 5-Gbit/s data encoding and transmission in free space using ul-trafast 2×2 green micro light-emitting-diode (Green Micro-LED) array”.

“In previous years, the research on the high-speed green micro-LED always kept a slow pace due to its bottleneck originating from both material and device designs. The newly announced Green Micro-LED array with unique design and package achieves the world's fastest record for visible light wireless data commu-nication of LED.” MOST said. “This result follows the developing trend of high-speed blue and red Micro-LEDs to complete the last research mile that enables the free-space optical wireless communication from all kinds of intelligent display instruments made of RGB-Micro-LED array.”

The paper was rapidly accepted for publication by the Optica (formerly the Optical Society of America), subsequently recommended by Professor Harald Haas with the University of Edinburgh in the United Kingdom, and selected from the nearly 10,000 papers each year published by the Optica Society as the focus report in “Spotlight on Optics” in, Optica. The “Spotlight on Optics” web page has been published for more than a decade, and only at most 1% of the near-ly 10,000 published papers in the whole year can be selected as the focus papers. This paper is one of only 2 of all chosen articles with Taiwanese academic institu-tions as the corresponding address in 2021.
