Eindhoven, Netherlands - April 14, 2026 - Photon Bridge and PHIX have announced a strategic partnership to accelerate the development and large-scale deployment of advanced optical laser sources designed for hyperscale AI data center infrastructure.
The collaboration focuses on advancing Photon Bridge’s dense wavelength division multiplexing (DWDM) external laser source transmit optical subassembly (TOSA), a key component enabling high-bandwidth optical interconnects. The technology is specifically targeted at co-packaged optics (CPO) and high-density interconnect architectures, which are increasingly critical for supporting next-generation AI workloads.
Under the partnership, Photon Bridge will lead end-to-end product development, including multi-wavelength laser design, photonic integration, packaging architecture, and thermal modeling. PHIX will contribute its expertise in advanced photonic packaging and manufacturing, helping transition the technology from prototype to high-volume production.
The companies aim to address one of the most pressing challenges in AI infrastructure: the growing gap between compute performance and data transfer capacity. As AI systems scale across massive GPU clusters, traditional electrical interconnects are increasingly unable to meet bandwidth and efficiency requirements, driving a shift toward optical solutions.
The DWDM-based external laser source is designed to enable multi-wavelength optical transmission, significantly increasing bandwidth density while maintaining energy efficiency. This capability is essential for hyperscale environments where large volumes of data must be transferred rapidly between processors, storage systems, and networking equipment.
Executives from both companies emphasized that the partnership creates a clear pathway to commercialization by combining design innovation with proven manufacturing scalability. The collaboration leverages PHIX’s established model of preparing photonic components for production readiness before scaling to volume manufacturing, reducing time-to-market and execution risks.
The initiative also reflects a broader effort to strengthen the European photonics ecosystem, with both companies based in the Netherlands and working closely within the regional innovation network. By aligning research, design, and manufacturing capabilities, the partnership aims to accelerate the availability of deployment-ready optical engines for AI-driven infrastructure.
Industry observers note that optical interconnect technologies such as DWDM and co-packaged optics are becoming foundational to the future of data centers, particularly as AI workloads continue to push the limits of conventional architectures.
The collaboration between Photon Bridge and PHIX underscores a growing trend in the data center industry toward integrating advanced photonics into core infrastructure, enabling faster, more efficient data movement at scale and supporting the continued expansion of AI computing systems.
