## Summary

Photon Bridge announced a €10 million financing round on October 21, co‑led by the Amadeus APEX Technology Fund and 360 Capital. Existing backers Innovation Industries, Faber and the Brabant Development Agency (BOM) also increased their stakes. The funds will support product development, customer qualification and the expansion of the Eindhoven team, which aims to grow from 15 to 20 employees by the end of 2026.

The company targets the light‑source side of AI data‑center optics, proposing a multi‑wavelength laser platform that multiplexes several lower‑power semiconductor lasers onto a shared fiber. According to the announcement, the design can deliver up to 40 mW of optical power per wavelength per fiber and support 8, 16 or 32 wavelength configurations using dense wavelength‑division multiplexing. First samples are slated for 2027, with volume manufacturing planned for 2028. Photon Bridge’s approach relies on fabless development, partnering with multiple indium phosphide foundries and OSATs to achieve semiconductor‑scale yields, a key concern as AI clusters demand millions of units annually.

## Key points

- Photon Bridge raised €10 million, round co‑led by Amadeus APEX Technology Fund and 360 Capital.
- The laser platform targets up to 40 mW per wavelength and 8‑32 channels for AI data‑center optical links.
- First samples expected in 2027; volume manufacturing planned for 2028, team to reach 20 staff by end‑2026.

## Why it matters

Efficient, high‑yield laser sources are essential for the bandwidth and energy needs of next‑gen AI clusters, and Photon Bridge’s architecture could enable semiconductor‑scale production.
