About Lightium
Lightium AG is a photonic foundry based in Schlieren (Switzerland) that manufactures photonic integrated circuits (PICs) based on thin-film lithium niobate (TFLN). The company offers foundry services ranging from rapid prototyping and multi-project wafer (MPW) runs to volume production on 200-mm wafers in a high-volume foundry environment. The TFLN platform is characterized by light modulation at over 100 GHz, low-voltage operation (Vπ ≤ 1 V) and a broad transparency window from 350 to 5,500 nm. The Process Design Kit (PDK) is available in four wavelength bands (C-band, O-band, 780 nm, 830 nm). Partners include PHIX (photonic packaging), MPI Corporation and Axiomatic_AI (AI-assisted PIC testing). Target industries are photonics, telecommunications and semiconductors.
