First production-ready TFLN photonic foundry emerges from CSEM spin-off

  • CSEM announces the incorporation of its spin-off CCRAFT in April 2025.  
  • CCRAFT is a new foundry manufacturing photonic integrated circuits—key components for optical communication, AI data centers, and quantum technologies. 
  • It is the first production-ready pure-play foundry in the world to offer chips based on Thin‑Film Lithium Niobate (TFLN) technology, one of the fastest growing platforms in photonics.
  • CCRAFT already delivers pilot production today and plans to expand its production lines in Neuchâtel to deliver millions of advanced photonic chips.
