The emergent thin-film lithium niobate on insulator (TFLN or LNOI) photonic integrated circuits (PICs) offer significant advantages in various applications due to their unique properties. This paper briefly explores recent advancements in TFLN PIC developments and their broad applications, emphasizing transformative capabilities in telecommunications and beyond. We highlight CSEM's pioneering initiative in establishing the first open access foundry for this technology, addressing challenges associated with limited access to manufacturing facilities and process design kits (PDK).
