IQE plc of Cardiff, UK reported that its wholly-owned subsidiary, NanoGaN Limited, has purchased and was assigned a portfolio of patents from Luxtaltek Corporation, a maker of LED chips and arrays based in Taiwan. The collection of 54 patents covers a variety of innovative technologies and applications based primarily on Quasi Photonic Crystals (QPC). IQE says that this Quasi Photonic Crystal technology complements the IQE Group’s development of NanoImprint Lithography, and extends the potential applications of NIL beyond IQE’s current focus on DFB lasers.
The company points out that the acquired patents have applications in optical components such as VCSELs and edge emitting lasers, silicon photonics, modulators, fiber optic systems, micro-LED displays, biosensors, and image sensors including Diffractive Optical Elements (DOE).
The IQE subsidiary NanoGan Limited agreed to make a one-time payment of US$500,000 for the purchase. The IQE Board plans to commercialize the new technology with the support of the company’s existing in-house NIL capability.
IQE’s chief executive, Dr Drew Nelson said, “Over the last few years, IQE has developed an exciting and strong IP portfolio, which, coupled with the expertise and manufacturing capability to commercialize these new materials technologies have uniquely positioned IQE as the clear global leader in providing advanced compound semiconductor technology solutions.”
