IQE plc (Cardiff, Wales) has launched 150mm-diameter wafers of indium-phosphide that are ready for the creation of distributed feedback (DFB) lasers. Such lasers are used in cloud data centre networks in support of AI and machine learning.

IQE has developed the 150mm DFB InP laser wafer platform in collaboration with Kelvin Nanotechnology Ltd. and the James Watt Nanofabrication Centre. Such laser products are used in optical interconnect technology to meet the requirements of generative AI and data intensive applications.

Peter Rabbeni, senior vice president of the Communications Infrastructure and Security Business Unit of IQE, commented: “Scaling our current laser materials technology to deliver a fab-ready service at this size provides an immediate competitive advantage and faster time to market.”

Brendan Casey, CEO of Kelvin Nanotechnology, commented: “We are delighted to be able to demonstrate a DFB grating technology fully deployed on a six-inch indium-phosphide platform with high yield and uniformity, and we look forward to working with IQE in bringing this capability to the market.”
