First customer adoption validates breakthrough tunable laser integration platform
Eindhoven, the Netherlands – 30 September 2025 – Photon Bridge, a pioneer in advanced photonic integration, today announced the debut of its integrated tunable laser photonic integrated circuit (PIC), powered by the company’s novel cantilever waveguide coupling technology. The device is the first commercial demonstration of Photon Bridge’s integration platform and will be used by OE Solutions as the laser engine inside its next-generation integrated tunable laser assembly (ITLA) modules. Qualification is ongoing, with broader PIC sampling to additional customers anticipated in Q4 2025. Module sampling from OE Solutions is anticipated in Q2 2026.
Unlike conventional approaches, Photon Bridge’s platform enables seamless combination of the optimal materials for each function—without restrictions on material choices—through a scalable, OSAT-compatible integration process. This flexibility allows the laser PIC to pair III-V gain and detection with low-loss silicon passive elements, all within a cost-efficient model ready for high-volume manufacturing.
The new tunable laser PIC integrates gain, SOA, filter, and wavemeter functions into a single device with a highly compact form factor. Samples already demonstrate linewidths below 100 kHz and full C-band tuning range, with product designs targeting a footprint of just 15mm2, delivering a fully integrated, highly cost-effective solution for customers. Beyond ITLAs, the same integration platform is designed to scale toward compact, fully integrated coherent subsystems, enabling a new class of miniaturized optical engines for both telecom and AI infrastructure.
Built on a silicon foundation, the platform also provides a direct path to integrating coherent and coherent-lite long-range scale-across links into datacenter switches in a footprint compatible with co-packaged optics (CPO). This opens the door to next-generation switch architectures where advanced optical engines are natively embedded, maximizing bandwidth density while minimizing power and cost.
This breakthrough comes at a pivotal moment for the industry. Explosive growth in AI datacenters is fuelling a global race to scale-across massive GPU clusters, creating unprecedented demand for faster optical interconnects. Photon Bridge’s unique integration technology directly addresses this challenge, combining performance, scalability, and efficiency in a way no other platform can.
“AI datacenters are racing to scale-across massive GPU clusters, creating exploding demand for compact, energy-efficient tunable lasers,” said Paul Marchal, CEO of Photon Bridge. “Our silicon-based integration platform is built for this moment—delivering the performance customers need today in ITLAs, while extending naturally to DWDM architectures, co-packaged optics (CPO) and fully integrated coherent links in next generation datacenter switches. Partnering with OE Solutions to bring this technology to market underscores both the strength of our platform and the credibility of our execution.”
OE Solutions is already integrating the new PIC into its ITLA, positioning it at the forefront of next-generation coherent communication systems.
“Photon Bridge’s integration technology is a genuine breakthrough,” said Y.K. Park, CEO at OE Solutions. “The ability to combine the best materials without compromise—and to do so with a scalable, cost-efficient process—enables compact, high-performance ITLAs and next-generation coherent modules. We’re excited to be the first to bring this platform into commercial products.”
With its unique integration platform, Photon Bridge is building the optical engines that will power the AI datacenters and global telecom networks of the coming decade.
Photon Bridge is present at ECOC 2025 at booth C4119, with a dedicated meeting and demo space at MR4 to connect with partners, customers, and industry leaders.
