Building the Future of Data Infrastructure

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.
