BaTiO₃ wafer targets co-packaged optics
La Luce Cristallina has released a beta version of its 200-mm barium titanate wafer designed to enable ultra-low-voltage electro-optic modulators for co-packaged optics and AI-scale photonic systems.
La Luce Cristallina has announced the beta release of its 200-mm (8-inch) barium titanate (BaTiO₃) wafer, offering customers an evaluation platform for next-generation electro-optic modulators used in telecommunications and data communications.
The company says the BaTiO₃ platform is designed to support the development of ultra-low-voltage photonic devices, addressing the growing bandwidth and power demands of AI-driven data centre infrastructure and co-packaged optics architectures.
According to La Luce Cristallina, the material can be integrated into standard CMOS silicon manufacturing processes, allowing semiconductor fabs to adopt the technology without significant changes to existing production lines.
BaTiO₃’s high Pockels coefficient enables efficient electro-optic modulation, making it attractive for high-speed photonic switching and signal processing.
Beyond data centre interconnects, the platform could support applications in quantum photonics, biosensing, and LiDAR systems, where high-speed and low-loss optical modulation are critical.
The company will showcase both its 200-mm and 50-mm BaTiO₃ wafers at the Optical Fibre Communication Conference (OFC) in Los Angeles from March 17–19.
