La Luce Cristallina releases beta 200-mm BaTiO₃ wafer

Technologies and Products

Silicon photonics manufacturer La Luce Cristallina announced that the beta version of its 200-mm (8-inch) barium titanate (BaTiO₃) wafer to help advance co-packaged optics architectures and address the bandwidth and power demands of AI-scale data centre infrastructure.

The BaTiO₃ platform can be cleanly integrated end-to-end into standard CMOS silicon manufacturing processes, facilitating rapid adoption without fab retooling. BaTiO₃’s extremely high Pockels coefficient (reaching up to ~1,300 pm/V in bulk single crystal) enables ultra-low-voltage electro-optic modulators across numerous photonics applications.

Due to these benefits, BaTiO₃ is emerging as a leading electro-optic material for low-loss, high-speed switching in quantum optical circuits, with PsiQuantum leveraging it to build quantum supercomputers

BaTiO₃’s ability to maintain operational efficiency in adverse conditions strongly positions it to support military and aerospace LiDAR use cases, with the LiDAR market projected to grow from $3.27 billion to $12.79 billion by 2030.

“The beta version of our barium titanate wafer marks another step toward advancing co-packaged optics amid the rise of AI, quantum photonics and other high-capacity applications,” said Agham Posadas, CTO and Co-Founder, La Luce Cristallina. “With this beta version, current and prospective customers can test-drive our solution’s capabilities and unlock the full potential of barium titanate for powering multiple generations of electro-optic innovation across diverse use cases.”
