La Luce Cristallina Advances Barium Titanate Technology
La Luce Cristallina has launched its 200-mm barium titanate (BaTiO3) wafer and opened a state-of-the-art fabrication facility in Austin, Texas. The facility expands capacity for wafer-scale fabrication of its crystal-on-glass BaTiO3 substrates, supporting growing demand from data centers, telecommunications, sensing, computing and integrated photonics markets.
With equipment provided by DCA Instruments, a Finnish manufacturer, the facility will enable closer collaboration with partners and customers worldwide through a secure U.S.-based supply chain, the company said.
La Luce Cristallina is currently taking orders for its 200-mm wafer, with delivery expected early in the first quarter of 2026.
La Luce Cristallina’s 200-mm wafer offers better speed, a smaller size and lower power consumption than silicon photonics modulators while addressing the integration challenges of alternative materials, the company said. The solution provides a high-performance, foundry-compatible, electro-optic platform that supports the capacity demands of AI workloads and high-density optical interconnects. The technology also supports emerging use cases in quantum computing, aerospace, and defense applications.
Based on radio frequency (RF) sputtering, to achieve scalability, La Luce Cristallina’s manufacturing approach allows it to produce multiple 200-mm wafers per day, which the company said outpaces other approaches to producing BaTiO3 on silicon.
The company said it maintains a secure supply chain, utilizing U.S.-sourced silicon and qualified international partners for silicon-on-insulator (SOI) wafers, ensuring reliable sourcing and mitigating the risks associated with overseas manufacturers. The solution also integrates cleanly with silicon manufacturing processes and avoids the chemical contamination issues associated with lithium niobate and similar materials.

Glossary
- barium titanate
- A crystalline material used in piezoelectric devices.
- wafer
- In the context of electronics and semiconductor manufacturing, a wafer refers to a thin, flat disk or substrate made of a semiconducting material, usually crystalline silicon. Wafers serve as the foundation for the fabrication of integrated circuits (ICs), microelectromechanical systems (MEMS), and other microdevices.
Here are key points regarding wafers:
Material: Silicon is the most commonly used material for wafer fabrication due to its excellent semiconductor properties, high purity,...
