Tower Semiconductor Ltd. (NASDAQ:TSEM) is an independent semiconductor foundry that provides technology, development and process platforms for integrated circuits. It also manufactures analog integrated circuits, key to speeding up data transfers and improving power efficiency in AI and data centre applications. On March 12, the company confirmed a successful demonstration of the 400G/lane modulator PH18DA integrated silicon photonics platform.

The demonstration, which was conducted in partnership with OpenLight, achieved a better than 3.5db extinction ratio using PAM-4 modulation format at 0.6 volts peak-to-peak drive voltage. The successful tests addressed critical challenges in data centre and AI optical connectivity, whereby silicon modulators cannot support 400G bit rates.

Tower Semiconductor’s ability to enable 3.2Tb solutions spanning CWDM wavelengths places it at the nexus of two rapidly expanding markets, AI infrastructure and silicon photonics. Likewise, it boasts as a competitive advantage in meeting the demands of next-generation optical communication since it can provide a scalable, manufactured solution.

“This is a significant step toward providing scalable, reliable, high-performance and manufacturable solutions for the next generation of optical communication technology,” said Russell Ellwanger, CEO of Tower Semiconductor. “By utilizing Tower’s PH18DA platform, this collaboration allows OpenLight’s heterogeneous integration technology to provide a secure path to higher speeds without the need for complex and expensive integration alternatives like Thin Film Lithium Niobate (TFLN), BTO or polymers.”
