NanoGaN purchases micro-LED applicable quasi photonic crystal patents from Luxtaltek

NanoGaN (a subsidiary of UK-based Eipwafer foundry and substrate maker IQE) announced that it has purchased a portfolio of 54 quasi photonic crystals patents from Taiwan's Luxtaltek for $500,000.

NanoGaN says that these newly acquired patents have applications in optical components - including Micro-LED displays. Other possible applications are in the fields of vertical-cavity surface-emitting lasers (VCSELs), modulators, silicon photonics, fiber-optic systems, biosensors and more. IQE believes that due to its existing in-house NIL capability, the firm is well positioned to commercialize the new technology.
