Tower Semiconductor and Marvell Ship Over 5 Million Coherent Photonic Integrated Circuits for AI Data Center Connectivity - Quiver Quantitative

Tower Semiconductor and Marvell have shipped over five million coherent photonic integrated circuits (PICs), marking a significant advancement in high-bandwidth, energy-efficient data center connectiv... Read original →

The shipment of over five million coherent PICs by Tower and Marvell signals silicon photonics’ transition from prototyping to volume deployment. This milestone pressures upstream suppliers to refine non-silicon integration for lasers and modulators, while compelling switch ASIC vendors to redesign SerDes architectures for optical latency profiles. Geopolitically, U.S. export controls on advanced packaging tools could inflate costs for V-groove-based 3D integration; though Tower’s Israel fab currently sidesteps U.S.-China tensions, expanded restrictions targeting photonic manufacturing would test its supply chain resilience. Rivals like Intel and GlobalFoundries may accelerate co-packaged optics efforts, while TSMC (Taiwan, China) could embed silicon photonics into its CoWoS platform to lock in AI customers. Within 18 months, surging demand for 800G/1.6T interconnects in AI clusters will grant pricing power to firms with co-optimized electro-optical design capabilities—leaving pure electrical I/O solutions increasingly obsolete.
