Photon Bridge and PHIX partner on DWDM laser sources for AI data centers

Photon Bridge, in Eindhoven, and PHIX, based in Enschede, both in The Netherlands, have announced a partnership to advance Photon Bridge’s high-performance DWDM external laser source known as Transmit Optical Sub-Assembly (TOSA), targeting co-packaged optics (CPO) and high-density optical interconnects for AI data center infrastructure.

Photon Bridge supports end-to-end product development, spanning multi-wavelength external laser source design, photonic integration platform, packaging architecture, and thermal simulation, underpinned by expertise across the optical module stack.

PHIX, described as a specialized photonic packaging house with a record of taking advanced designs from prototype through to volume production, offers complementary capabilities that support Photon Bridge’s path from advanced design to a deployment-ready modules. PHIX’s model, which bridges early-stage development to high-volume manufacturing, provides a route to scale for the TOSA.

The partners stated that the collaboration “reflects a shared commitment to developing a sustained working relationship within the Dutch photonics ecosystem, and to accelerating the availability of high-performance optical engines for next-generation AI infrastructure.”

John Anderton, CCO of Photon Bridge, commented, “Photon Bridge is building a true product company, spanning from the photonic chip to the fully integrated module. The market needs a packaged, deployment-ready external laser source, and that is exactly what we are delivering. PHIX’s expertise and their model of developing packages to manufacturing readiness before transferring to volume production gives us a clear and reliable path to scale.”

Jeroen Duis, CTO of PHIX, said, “We are pleased to partner with Photon Bridge on their TOSA development. Their full-stack photonic integration approach aligns strongly with the demands of CPO and AI interconnects. At PHIX, we enable innovative photonics companies to transition efficiently from advanced design to volume packaging.”

About the partners

Photon Bridge was founded to address what it sees as “the growing gap between compute performance and data throughput, where optical interconnects have become critical to sustaining AI growth.” 

The company develops multi-wavelength digital light engines for DWDM data center optics, enabling the bandwidth scaling required for next-generation AI and high-performance computing infrastructure. Its patented cantilever waveguide platform unifies lasers, silicon photonics, and optical control into a single, production-ready architecture.

PHIX offers assembly services and contract manufacturing for devices based on photonic integrated circuits (PICs). It builds optoelectronic modules based on all major PIC technology platforms, such as indium phosphide, silicon photonics, silicon nitride, and lithium niobate.
