Thin-Film Lithium Niobate Foundry Services by CSEM
CSEM supports the photonic community with various services based on its standardized TFLN PIC platform, dependable process design kit (PDK) and a 150 mm wafer-scale fabrication process, which includes PIC design, manufacturing, and testing.
CSEM was among the first to introduce an open-access foundry service for standardized TFLN PICs (Thin-Film Lithium Niobate on Insulator Photonic Integrated Circuits), designed specifically for prototyping, and research and development. The distinctive features of this service include a unique combination of three device layers, two metallization steps, cladding, back-end-of-line opening steps, and seamless chip facets integrated into a monolithic PIC platform.
This integration opens up a myriad of possibilities for intricate PIC designs, as well as hybrid and heterogeneous integration. Moreover, it facilitates easy electrical and packaging interfacing.
Our state-of-the-art technology and expertise in the PIC domain ensure superior quality and performance for applications in telecommunications, data centers, quantum, and beyond. Now is the time to partner with CSEM to leverage the potential of TFLN in your innovative projects.

Process design kit for TFLN PICs
CSEM TFLN PIC foundry services is supported by a dependable process design kit (PDK) on telecommunication C-band. The PDK encompasses a set of active and passive building blocks, technology layers and design guide documentation.
Furthermore, CSEM provides the PIC designer with parametric cells (PCell) for the building blocks. This enables the designer to turn the standardized components into customized ones (in compliance with the fabrication design rules), easing the layouting and circuitry of the customized PICs.
CSEM’s PDK is now available at LUCEDA.

Chercheur scientifique laboratoire de photonique quantique
Nous soutenons fortement la démarche du CSEM visant à construire un service de fonderie pour cristaux photoniques en niobate de lithium, car nous croyons que cela aura un impact majeur sur l’industrie et sur la communauté scientifique. Nous avons une chance incroyable d’avoir été associés très tôt à cette démarche et de travailler avec le CSEM, dans la mesure où ses capacités étendent et accélèrent notre recherche dans le domaine de la photonique quantique intégrée.
Richard Phelan
Responsable conception laser
Plusieurs projets réalisés avec le CSEM nous ont permis d’effectuer des avancées substantielles dans les lasers à semi-conducteurs et nous ont ouvert de nouvelles opportunités commerciales dans les lasers à raie ultrafine pour les applications LIDAR. Les discussions avec les experts du CSEM nous ont apporté de nombreuses idées nouvelles et des retours utiles pour différentes applications telles que la métrologie et la détection.

Directeur technique
Le CSEM possède une connaissance et une maîtrise incroyables des systèmes optiques permettant de mesurer les signes vitaux. Il a utilisé ce savoir-faire pour nous aider à atteindre notre objectif, nous permettant ainsi d’améliorer considérablement le logiciel OptiBP et, par conséquent, la gestion de l’hypertension à l’échelle mondiale.
