Tower Semiconductor and Alcyon Photonics Announce Collaboration to Accelerate Integrated Photonics
Innovation
Providing Silicon-Validated Photonics IP Based on Tower's SiPho Platform for Datacom, Telecom
and Sensing Markets
MIGDAL HAEMEK, Israel, and MADRID,
Spain, March 25, 2025 – Tower Semiconductor [NASDAQ/TASE: TSEM], the leader in high-value analog semiconductor foundry solutions, and Alcyon Photonics, a leader in integrated photonics design, today announced their collaboration to accelerate photonics integration. Through this
partnership, Alcyon Photonics will provide customers with silicon-validated, high-performance photonic building blocks (BBs) and circuits to accelerate the development of next-generation optical applications.
Leveraging Tower Semiconductor’s advanced, high-volume SiPho platform, this collaboration enabled the development of robust,
silicon-proven photonic IP, facilitating a seamless transition from concept to production while ensuring exceptional performance, reliability, and manufacturability. Alcyon’s proprietary design techniques, optimized for Tower’s SiPho technology,
provide significant competitive advantages, including outstanding stability that maintains channel drifts below 3 nm even with fabrication variations of up to 30 nm. Joined with Tower’s high-volume SiPho manufacturing capabilities, this partnership
provides customers with consistent, high-yield results, enabling efficient and cost-effective photonic integration.
"We are thrilled to partner with Tower Semiconductor to deliver best-in-class photonic IP to the market," said Jimena García-Romeu, CEO of Alcyon Photonics. "By combining our advanced photonics design expertise with Tower’s industry-leading foundry SiPho technology, we are
enabling customers to create compelling new applications with a faster and more predictable development cycle."
This collaboration brings specific advancements to market, including CWDM solutions optimized for data center networking in the O
band, which support high-capacity and high-performance optical interconnects. Additionally, the partnership is driving advancements in coherent communications across the C+L bands, expanding bandwidth, enhancing scalability, and future-proofing
optical networks.
"Tower Semiconductor is committed to fostering a strong ecosystem that supports our customers in accelerating their photonic
innovation," said Dr. Samir Chaudhry, Vice President of Customer Design Enablement, Tower Semiconductor. " Collaborating with Alcyon Photonics
as an IP partner further reinforces Tower Semiconductor’s leadership in silicon photonics, strengthening our offering by providing validated, high-performance photonic components that will help drive the next wave of integrated photonics
applications."
