MIGDAL HAEMEK, Israel and GRENOBLE, France, Feb 20, 2026 – Tower Semiconductor and Scintil Photonics announced the availability of heterogeneously integrated Dense Wavelength Division Multiplexing (DWDM) laser sources for AI infrastructure. The devices use Scintil’s SHIP (Scintil Heterogeneous Integrated Photonics) technology to integrate photonic components on a single platform.
Tower’s silicon photonics platform forms the foundation of SHIP, which integrates monolithic laser sources through heterogeneous integration. The design targets DWDM requirements in AI infrastructure. DWDM lasers serve as a central component in Co-Packaged Optics (CPO) architectures used in advanced AI systems. CPO designs focus on bandwidth density, lowering tail latency and reducing energy per bit. These architectures also support improved GPU utilization in hyperscale data center environments.
“The scale-up networking opportunity is about to increase significantly as these server interconnects move to multirack CPO. Scale-up networking will consume an increasing portion of AI Networking’s $200B 2030 market as the market moves towards optical architectures, reducing the constraints on beachhead and copper bandwidth limitations per GPU/XPU,” said Alan Weckel, founder and technology analyst at 650 Group, LLC. “Manufacturing and foundry to vendor alignment is the key to unlocking the CPO market to ensure the reliability and volumes that Hyperscalers need to hit their AI goals.”
Scintil’s SHIP technology has been validated on Tower’s silicon photonics platform. LEAF Light is a DWDM-optimized integrated laser source built with SHIP. Tower manufactures silicon photonics across multiple sites, supporting capacity and supply continuity for hyperscale data center deployments. The collaboration supports customer evaluations for DWDM CPO programs and defines a 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.”
“We deeply value our long-term partnership with Scintil and are excited to bring this revolutionary monolithic DWDM laser technology to market to enable next generations of scale-up architectures,” said Dr. Ed Preisler, VP and GM of RF business unit at Tower Semiconductor. “Scintil’s platform complements our PH18M platform already in mass production for optical transceivers at our facilities worldwide.”
