Photon Bridge raises €10 million to develop laser sources for AI data centers

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.
