Lumiphase

Lumiphase is a photonics technology company based in Zurich, Switzerland, that designs and manufactures silicon photonic integrated circuits (PICs) enhanced with barium titanate (BTO). The company positions BTO as the key material at the core of all its products, citing its strong electro-optical effect and energy-efficient modulation, while leveraging an established silicon photonics (SiPh) platform for CMOS compatibility and reliability. Lumiphase's offering spans from PIC design to known-good dies, with a proprietary thin-film BTO production technology intended to enable scalable, high-volume manufacturing. Its BTO+SiPh chips are aimed at high-density, low-power applications, with tailored data rates reaching 200G per lane and beyond. Target applications include high-speed optical modulators, pluggable transceivers, and GPU interconnects, addressing optical communication, networking, and computing markets. The company markets itself as delivering leading-edge integration, efficiency, and scalability to customers worldwide, and it recruits talent to build photonic products for optical communication, networking, and computing. As of the available evidence, Lumiphase is a private company headquartered in Zurich, Switzerland.
