The given technology involves a novel method in achieving high-efficiency group III-nitride light-emitting diodes (LEDs) and laser diodes emitting in the visible regime (wavelengths between 420nm and 650nm) for use in solid-state lighting and medical applications.

The current state of the art suffers from poor performances due to low optical gain. The given technology allows for a high-efficiency blue-green-red media, which can be integrated into a single chip for achieving high-performance solid-state lighting. The technology will have the ability to replace bulky and expensive lasers as a highly-efficient laser in the green regime.

A U.S. utility patent application and patent cooperation treaty (PCT) have both been filed. For more information on this licensing opportunity, visit Lehigh University.
