La Luce Cristallina (LC) is a manufacturer of Si-integrated high-performance materials for silicon photonics, focused on barium titanate (BaTiO3) materials enabling electro-optic modulators for low power and medium to high frequency photonic applications such as field sensors including biosensors, optical interconnects, space applications, quantum information (QI), and neuromorphic computing (AI). We’re leading the transition from silicon and LiNbO3 to high-performance BaTiO3 as we shape the future of photonic materials with the move towards optical interconnects, sensing, and optical computing. 

Our flagship product is optically active crystal-on-glass (COG) BaTiO3 integrated on silicon. Materials produced by LC come in the form of wafers/substrates. These are produced as thin disks that are 200 mm in diameter and are less than 1 mm thick. These substrates can then be patterned into devices and cut into chips to make photonic integrated circuits (PICs) for Si photonics. We offer unique and competitive solutions for miniaturizing photonic chips, greatly improving their performance, and reducing their energy usage.
