Israeli foundry Tower Semiconductor and French Heterogeneous Integrated Photonics Scintil Photonics have announced the world’s first heterogeneously integrated Dense Wavelength Division Multiplexing (DWDM) laser sources for AI infrastructure. Specifically, it makes use of Scintil’s Heterogeneous Integrated Photonics (SHIP) technology.

SHIP leverages Tower’s high-volume silicon photonics platform and combines it with heterogeneous integration monolithic laser sources. Therefore, is capable of meeting the most demanding DWDM technical requirements for AI.

DWDM lasers are an essential component of co-packaged optics (CPO)-based next-generation of AI infrastructure. Specifically, they aim to deliver ever-growing bandwidth density, ultra-low tail latency, and lower energy per bit while improving GPU use and hyperscaler ROI needed in the agentic AI era.

Meets Challenges of Next-Generation Hyperscale AI

As AI data center growth accelerates, hyperscalers need networking solutions that reduce power, improve utilization, and scale with the next generation of models.

DWDM CPO, with higher bandwidth density, lower energy per bit, and ultra-low tail latency, are where the industry is heading. LEAF Light is the first production-ready DWDM laser source that uses heterogeneous integration to monolithically integrate active lasers and established silicon photonics on a single chip.

Scintil’s SHIP technology has been validated on Tower’s silicon photonics platform. LEAF Light is the industry’s first DWDM-optimized, intelligent integrated laser source fabricated with SHIP. Tower Semiconductor’s multi-site silicon photonics manufacturing footprint provides resilient capacity and supply continuity aligned with hyperscale deployment needs.

This positions the partnership for high-volume hyperscale deployment with the capacity flexibility and supply continuity required at scale. The collaboration supports customer evaluations for DWDM CPO programs, establishing a defined path from qualification to volume manufacturing.

“Next-generation AI infrastructure demands optical interconnects that deliver more bandwidth per fiber at lower power per bit,” said Matt Crowley, Chief Executive Officer of Scintil Photonics. “DWDM co-packaged optics meets that bar. LEAF Light brings the DWDM laser source technology; Tower’s SiPho platform brings the manufacturing scale. With SHIP™ now validated on Tower’s production lines, customers have a path from evaluation to millions of units per month.”
