Coherent unveils broad InP technology lineup for next-gen photonics
Coherent is set to spotlight its latest Indium Phosphide (InP) technology developments at OFC 2026, positioning the platform as a key enabler for next-generation optical networking. The company will present a broad portfolio of components and subsystems designed to meet the growing demands of AI-driven data center infrastructure.
With data traffic surging and energy efficiency becoming critical, the announcement highlights how InP continues to underpin high-speed optical connectivity. For eeNews Europe readers, the developments offer insight into how photonics suppliers are scaling performance and manufacturing to support AI workloads and future network architectures.
Expanding InP portfolio targets high-speed networks
At the core of Coherent’s showcase is a wide-ranging InP-based portfolio that spans lasers, modulators, photodiodes, and integrated subsystems. The company is introducing a 400mW high-power continuous-wave laser aimed at co-packaged optics (CPO) and silicon photonics pluggables, alongside 200G electro-absorption modulated laser (EML) solutions targeting 1.6T transceivers.
The lineup also includes differential EMLs (D-EMLs) capable of enabling 400G per lane performance for emerging 3.2T pluggable modules, as well as high-speed 200G and 400G photodiodes. Beyond discrete components, Coherent is advancing scale-across transmission technologies such as nano-Integrated Tunable Laser Assemblies (nITLA) and high-capacity IQ modulators supporting 800G and 1.6T applications.
Together, these offerings form a comprehensive InP-based solution set addressing scale-out, scale-up, and scale-across architectures. This positions the technology as a versatile foundation for both pluggable transceivers and optical transport systems.
Manufacturing scale and AI demand drive momentum
Coherent is also emphasizing its manufacturing capabilities as a key differentiator, particularly as demand accelerates from AI infrastructure deployments. The company is ramping 6-inch InP wafer production across facilities in Sweden, the United States, and Switzerland to ensure supply continuity.
“InP technology is central to high-performance optical connectivity,” said Beck Mason, Executive VP – Semiconductor Devices at Coherent. “Our expanding InP platform, from high-power lasers and advanced modulators to photodiodes and integrated subsystems, demonstrates our commitment to delivering the performance, scalability, and manufacturing depth required for AI-driven networks. We are significantly ramping 6’’ InP production across our fabs in Järfälla (Sweden), Sherman (U.S.), and Zürich (Switzerland), reinforcing supply continuity and scalability for customers deploying next-generation optical systems”.
The company’s presence at OFC 2026 will provide a closer look at how its expanding portfolio and production footprint are aligning with industry needs for higher bandwidth, lower power consumption, and scalable optical interconnects.
