Bringing the exciting functionality of crystalline oxides to semiconductors
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, 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 amid industry shifts in optical interconnects, sensing, and high-performance computing.
