Blue LEDs, however, are not available at this time in micro-sizes, Lin said, making it virtually impossible to use in smaller items, such as heat-mounted microdisplays and cell phone displays.

Taking advantage of a blue GaN micro LED, researchers succeeded in operating a free-space optical link at over 7 Gb/s, possibly functioning as a precursor of a super-speed LiFi type link.

“Mojo Vision’s advancements establish a road map for commercial scaling of micro-LED technology using processes compatible with industry-standard 300mm fabs,” said Dr. Rajeeva Lahri ...
