On May 13, 2026, Israeli foundry Tower Semiconductor announced a long-term silicon photonics (SiPho) supply contract worth $1.3 billion with its largest customer, corresponding to 2027 revenue. The customer has prepaid $290 million to lock in critical production capacity and has committed to placing larger wafer orders in 2028, with additional prepayments due before January 2027.

Demand Exceeds Contracted Volume

Tower disclosed that the $1.3 billion figure represents only the minimum committed volume from the customer in question, with actual shipments expected to exceed this amount. Total customer demand for 2027 is further bolstered by strong forecasts from more than 50 active silicon photonics clients, spanning applications including data center optical interconnects, AI infrastructure, and advanced packaging.

The announcement coincided with Tower's better-than-expected first-quarter results. In Q1 2026, the company reported revenue of $414 million, up 15% year-over-year, and net profit of $65.03 million, surging 62% year-over-year. Silicon photonics revenue tripled compared with the prior year, establishing itself as the core growth engine.

Technology Roadmap and Capacity Expansion

Chief Executive Officer Russell Ellwanger stated that the multi-year customer commitments reflect firm confidence in Tower's differentiated, multi-generation silicon photonics technology roadmap. Tower Semiconductor is evolving from its current high-volume pluggable optical transceivers toward next-generation near-package optics (NPO) and co-packaged optics (CPO) solutions. CPO technology, which co-packages optical engines with compute chips, significantly enhances bandwidth density while reducing power consumption—a critical direction for next-generation hyperscale data centers. Concurrently, Tower is advancing cutting-edge technologies including 400 GHz/channel modulators, optical circuit switches, and 3DIC hybrid bonding to meet AI infrastructure's extreme demands for bandwidth and energy efficiency.

To support this accelerating demand, Tower is substantially expanding silicon photonics capacity across multiple global fabs in Israel, the United States, Japan, and its Italian joint-venture facility. The company explicitly identifies silicon photonics expansion as foundational to achieving its 2028 financial model—namely, the strategic targets of $2.8 billion in annual revenue and $750 million in net profit.
