PhotonLinkTM
The integrated optics platform for AI connectivity
PhotonLink brings together the critical photonic technologies needed to connect AI infrastructure, from light generation and conditioning to optical coupling, transmission, and detection. Purpose-built for CPO (Co-Packaged Optics), NPO (Near-Packaged Optics), and emerging chip-to-chip architectures, it enables higher bandwidth density, lower energy per bit, reduced latency, and manufacturability at AI scale.
Generate
Create the photon
High-performance light sources provide the optical power needed for next-generation AI interconnects in compact and energy efficient design. PhotonLink Generate brings together InP laser and GaAs VCSEL technologies for CPO, NPO, and other highly integrated optical architectures, optimized for production at AI scale.
Shape the signal
Precision optics efficiently couple and condition light while protecting the laser from unwanted reflections, while in-house designed Silicon Photonics performs modulation and photodetection functions. PhotonLink Shape combines advanced materials and integration technologies for reliable optical performance.

Guide
Guide the photon
Specialty fiber, micro-optics, and precision assemblies route light from the laser to the receive engine in CPO / NPO architectures. PhotonLink Guide Precision-aligned solutions simplify integration, protect fibers, and improve serviceability while maintaining alignment, polarization, and coupling efficiency in dense optical systems.
Receive the photon
High-speed photodetectors and ICs convert optical signals back into electrical data for the xPU or switch. PhotonLink Receive brings together detector technologies, dense arrays, silicon photonics, and custom designs for compact and efficient integration at scale.
