Sesame Summit 2026 – application open
We make data centers run faster and more efficiently with our next-gen photonic chips
Lightium AG is a Swiss startup offering Photonic Integrated Circuits (PIC) foundry & design services based on its proprietary, production-grade, thin-film lithium niobate (TFLN) platform. Data centers are forecasted to consume up to 10% of the world’s electricity and handle 100x more data by 2030. Lightium’s TFLN platform offers greater performance while tackling energy efficiency concerns across versatile sectors like datacom, satellite communication, and quantum computing. "Current semiconductor-based technologies powering data centers' communication have reached their limits - they cannot run faster or more efficiently. Lightium uses TFLN to solve this problem, and we have now developed the manufacturing capability to provide this technology at scale for the industry. What used to be limited to academic and R&D cleanrooms has now become an accessible reality for the industry to adopt."
