Lightium AG

AI is growing faster than our data infrastructure can support. Compute speeds have outpaced communication bandwidth 1,000x in the past two decades. Silicon photonics, while dominant, hits a physical ceiling at 800 Gb/s, and power costs are exploding. Bandwidth, not compute, is now the bottleneck.

Lightium is the first open-access 200 mm foundry for Thin-Film Lithium Niobate (TFLN), the leading post-silicon photonic platform. We manufacture ultra-fast photonic chips for data, telecom, quantum, and defense. Our 200 mm wafer platform, Western-based supply chain, and IP-safe model provide customers with full control, unmatched performance, and a short time-to-market.

We are positioned at the forefront of photonics, enabling ultra-high speeds for our connected world.
