IQE enhances AI connectivity for data communications with advanced high-speed portfolio expansion

IQE plc (AIM:  IQE, "IQE" or the "Group"), the leading global supplier of compound semiconductor wafer products and advanced material solutions, is pleased to announce a strengthened portfolio of high-speed optical connectivity epiwafers to address increasing demands for artificial intelligence (AI), cloud, carrier, and data-intensive workloads.

These products are designed to meet the demands of AI and data centres now and in the future, while also increasing energy efficiency. The new offerings are:

  • The industry’s first foundry epitaxy service for 1310 nm Quantum Dot Lasers (QDL), available on both GaAs and Si, with PIC and CMOS platform compatibility to enable customers to develop next generation high data payload optical transceivers for greater performance and energy efficiency within data centres
  • Launch of a 56G 850 nm VCSEL reference design for pulsed amplitude modulation (PAM-4) optical transmission in data centre and enterprise short-reach multimode fiber (MMF) applications
  • Release of a 6” InP based PIN photodetector platform, complementing our 6” InP FP, DFB and EML signal laser offering, for customers prototyping photonics devices at disruptive larger wafer diameters, enabling the industry to scale and meet the future demands of datacom whilst driving economies of scale

Mark Furlong, Executive Vice President, Business Development, commented:

Datacom is undergoing a rapid transformation as it needs to meet the demands of generative AI and its high-speed data processing. Our strengthened portfolio is at the forefront of an industry drive for faster, more efficient and cost-effective data connectivity solutions. We are enabling our customers to develop a competitive advantage to transform optical networks at the heart of AI engines and next-gen compute while also generating economies of scale and supporting the need for more sustainable solutions.”
