About Us

Saphlux, Inc. develops, manufactures, and supplies semi-polar gallium-nitride (GaN) materials for nitride-based solid-state lighting and power devices. Major applications include high power blue LEDs, green LEDs, Micro-LEDs, laser diodes, VCSELs, IGBTs, etc. 

Benefits of semi-polar materials have long been proven in addressing the fundamental bottlenecks in first generation c-plane GaN materials such as efficiency droop, green gap and wavelength shift in LEDs and lasers. However, the mass-production of large-area, high-quality and low-cost semi-polar GaN materials has been rather challenging.

Based on the research from the Nitride Group at Yale University, Saphlux was founded in 2014 by Prof. Jung Han and Dr. Chen Chen to resolve these problems. The company successfully developed the world's first stacking-fault-free semi-polar GaN-on-sapphire materials. Raised over $11 million from Venture Capitals, Saphlux has now built a dedicated production line to mass-produce 4-inch (20-21) GaN-on-sapphire templates for industry clients.
