What changed from existing technology?
This study introduces a high-performance green laser diode that can be used for fast and reliable communication through the air and underwater, solving long-standing issues with green light technology.
This is the first demonstration of a GaN-based green laser diode with improved efficiency and stability, overcoming the 'green gap' through advanced material engineering and device design.
