La Luce Cristallina

Founded and headquartered in Austin, Texas, La Luce Cristallina is a U.S.-based innovator in silicon photonics materials and barium titanate (BaTiO₃) electro-optic platforms. The company develops scalable, high-performance substrates that form the basis for next-generation photonic and optoelectronic devices used in data centers, telecommunications, sensing, aerospace, and quantum computing. Its advanced wafer-scale manufacturing processes and secure U.S.-based supply chain are helping to establish a sustainable foundation for the domestic production of high-value photonic materials.

Through proprietary semiconductor innovation, La Luce Cristallina utilizes a specially prepared single-crystal epitaxial oxide layer formed directly on silicon. This process allows the company to integrate most functional oxides on silicon and other semiconductor platforms. By combining high-rate oxide deposition with exceptional crystallinity, La Luce Cristallina can produce optical-grade BaTiO₃ on silicon or SiO₂/Si at the precise thicknesses required for modern photonics applications. This breakthrough capability supports the transition from traditional materials such as lithium niobate toward more efficient and scalable electro-optic platforms.

The company’s flagship product is an optically active 200 mm crystal-on-glass (COG) BaTiO₃ wafer integrated on silicon. Produced as thin disks measuring less than one millimeter thick, these wafers provide the foundation for photonic integrated circuits (PICs) used in advanced silicon photonics. By enabling further miniaturization of photonic chips, La Luce Cristallina’s substrates improve device reliability, reduce energy consumption, and optimize spatial efficiency—key factors driving performance in high-bandwidth applications across AI data centers, telecommunications, and quantum computing.

With the ability to produce multiple 200 mm wafers per day through advanced RF sputtering, La Luce Cristallina offers a scalable, foundry-compatible, electro-optic solution designed to meet growing global demand for secure and sustainable photonic materials. The company continues to collaborate closely with leading U.S. universities and research organizations, advancing material performance benchmarks and enabling a new era of innovation in integrated photonics.
