IN Brief:
- Photon Bridge has adopted CPFC as the InP foundry partner for its multi-wavelength external laser sources.
- The roadmap covers 8, 16, and 32-wavelength light engines with optical output above 30 mW per wavelength.
- The partnership is aimed at scaling photonic engines for AI infrastructure, co-packaged optics, and advanced sensing.
Photon Bridge has signed up the Canadian Photonics Fabrication Centre as the indium phosphide laser foundry partner for its multi-wavelength external laser sources, giving the Dutch photonics company a production-grade route for the laser side of a platform aimed at AI infrastructure and advanced sensing.
The partnership matters because external laser sources are becoming a key building block in higher-density optical interconnect architectures, especially where co-packaged optics and wavelength multiplexing are being used to raise bandwidth without multiplying fibre count and system complexity. Photon Bridge’s platform is built around a thick-silicon integration approach intended to combine lasers, silicon photonics, and optical control in a manufacturable architecture rather than a lab-optimised one.
According to the companies, CPFC is supplying high-power InP laser wafers supporting Photon Bridge’s roadmap for 8, 16, and 32-colour multiplexed sources with more than 30 mW per wavelength. CPFC brings more than 20 years of foundry experience and pre-commercial production capability in III-V photonic devices, which gives the tie-up more industrial weight than a typical development partnership.
Photon Bridge said its approach is aligned with outsourced semiconductor assembly and test flows, with relaxed tolerances intended to improve manufacturability, yield, and cost at volume. That makes the announcement less about a single source agreement than about whether external laser engines can move into a more repeatable supply model as optical links scale. More on the platform is available via Photon Bridge’s website.
