Enabling Foundry Ready BaTiO₃ Photonics: Advances and 300 mm Wafer Manufacturing
Barium titanate (BaTiO₃, BTO) is rapidly transitioning from an emerging research material to a leading platform for high performance electro optic modulators. Breakthrough results from 2024–2026 demonstrate that BTO can outperform silicon, lithium niobate, polymers, and other photonic materials in speed, power efficiency, and device density—key metrics for next generation communications and computing. Its strong Pockels response and compatibility with integrated photonics position BTO as a compelling candidate for commercial deployment. DCA Instruments has accelerated this trajectory by delivering the first 12″ (300 mm) BTO wafer production systems with full foundry compatibility, enabling scalable manufacturing for advanced photonic devices.

Sabina is the Sales Director at DCA Instruments in Finland. She joined the company in 2016 as the Sales & Research Manager and has since been involved in various aspects of the industry, including research & development, sales & marketing, project management, and technical support. Prior to her role at DCA Instruments, Sabina was a post-doctoral researcher at University College London (UK) from 2013 to 2016. During her tenure, she led a group focused on the fabrication of optoelectronic devices using III-V nanostructures on silicon. Despite being awarded the prestigious Royal Academy of Engineering Fellowship, she chose to pursue a career in the industrial sector. Sabina earned her PhD from Queen Mary University of London between 2009 and 2013, where she developed nanostructured ZnO optoelectronics. She has co-authored over 17 peer-reviewed publications.
