LIGENTEC is a Swiss based manufacturing partner, offering low loss SiN Photonic Integrated Circuits (PICs) for industries such as Quantum technologies, LiDAR, Communications, Space and Sensors. Due to its high confinement, the thick nitride waveguides and resonators have low bending losses and excel even in high power applications from the visible to the mid-IR. The main application areas for this advanced silicon photonics low loss technology include coherent telecommunication, LiDAR, metrology, supercontinuum generation, spectroscopy, sensing and microwave photonics. LIGENTEC’s All Nitride Core Technology platform is fully CMOS compatible, thus allowing us to offer ramping up to high volumes benefiting from the scale of the semiconductor industry.


LIGENTEC’s silicon nitride technology enables products based on integrated photonics and allows companies and research institutions to fabricate their own designs.

LIGENTEC offers a foundry service for our proprietary fabrication technologies in silicon nitride which are operated by our process engineers.

With our partner network we also offer design and packaging services.


  • Dedicated Engineering Runs: LIGENTEC offers dedicated runs to secure the full space on one or several wafers and can be started at any time by the customer.
  • MPW (Multi project Wafer Runs): LIGENTEC offers Multi Project Wafer (MPW) runs especially for small businesses and research institutions allowing them to share the space on the reticle, which keeps the costs down.

These runs, provided five times a year, are particularly interesting for getting a taste of our All-Nitride core technology.
