Nvidia Invests $2B in AI Data Center Photonics

🔑 Enhanced Key Takeaways

• •Nvidia announced a parallel $2 billion investment in Lumentum alongside the Coherent deal, totaling $4 billion to secure silicon photonics supply[1][2][5].
• •Each partnership includes Nvidia's multibillion-dollar purchase commitments and future capacity rights for advanced laser components and optical networking products[1][2][3].
• •Coherent and Lumentum plan to expand U.S.-based manufacturing and R&D facilities with the investments[1][2][3].
• •The deals build on Nvidia's 2025 unveiling of Spectrum and Quantum switches using co-packaged optics to reduce power consumption by integrating transceivers directly into switches[1].

🛠️ Technical Deep Dive

• •Nvidia's next-gen Spectrum and Quantum switches employ co-packaged optics (CPO), integrating optical transceivers directly into the switch package to eliminate pluggable modules and cut power consumption[1].
• •Designs still rely on external laser modules as light sources for the integrated optics on the switch side, while sticking with pluggable optics on the NIC side[1].
• •Focus on silicon photonics for InP laser sources, optical engines, pluggable transceivers, laser sources, and optical circuit switches to enable ultrahigh-bandwidth, energy-efficient AI data center connectivity[1][2].
