Tower’s advanced silicon photonics platform enables high bandwidth,
energy efficient data center connectivity
MIGDAL HAEMEK, Israel, June 18, 2026 – Tower semiconductor (NASDAQ/TASE: TSEM), the leading foundry for high-performance analog semiconductor solutions, today announced a major milestone. The company, in partnership with Marvell Technology, has shipped more than five million coherent photonic integrated circuits (PICs) to Marvell customers worldwide, delivering advanced, high-performance photonics solutions to meet the growing bandwidth and efficiency demands of AI-driven data center interconnect (DCI) networks.
Coherent PICs are complex because they need to control the phase and polarization of light, not just the amplitude. The design and process requirements for these PICs are much more stringent compared to simpler direct-detect chips.
“As applications and requirements for optical transceivers continue to evolve, photonics platforms must evolve to meet these demands. This is especially true in the field of coherent optical transceivers,” said Dr. Ed Preisler, vice president and general manager of the RF Business Unit at Tower Semiconductor. “We are proud to partner with Marvell to continue leading the way in this field.”
Tower has worked with Marvell to advance next-generation coherent technologies, including process capabilities such as the integration of non-silicon materials, the 3D integration of electronics, and enabling advanced optical packaging such as V-Grooves, which serve to extend the performance and functionality of silicon photonics platforms.
“This milestone demonstrates the strength of our collaboration,” the spokesperson said Dr. Radha Nagarajan, Senior Vice President and Chief Technology Officer, Optical Engineering, at Marvell. “As one of our key ecosystem partners, we look forward to continuing to work with the Tower team to advance the next generation of coherent technologies for scale across data center architectures, giving customers the latest efficient, high-performance photonics technologies to power their advanced AI workloads.”
