In recently-published testing results Crystal IS demonstrated for the first time its unique diodes fabricated on a proprietary Aluminum Nitride (AlN) substrate.

“Previous efforts to develop practical LEDs at this wavelength have proven to be very difficult,” said Crystal IS CTO Leo Schowalter. “Most workers in the field have used conventional substrates, such as sapphire as the starting material, and have struggled to produce commercially viable lifetime and power results. Today we are demonstrating that we have overcome many of those issues.”
