Main advantages using silicon nitride structures from LIGENTEC


  • high thickness
  • low-loss waveguides
  • low-loss fiber chip coupling
  • low surface roughness
  • transparent from visible to mid-IR


Light generating technologies using planar photonics

Ligentec is an expert in offering photonic chips with silicon nitride thickness above 600nm maintaining very low propagation loss. Our thick nitride is transparent from the visible to mid-IR and does not suffer from two photon absorption. Due to its good confinement thick nitride waveguides and resonators have low bending losses and excell in high power applications even in the mid-IR.

The main application areas using thick silicon nitride integrated photonics include coherent telecommunication, filters, supercontinuum generation, pulse generation, spectroscopy, sensing and microwave photonics.

With its silicon nitride chips Ligentec enables products based on integrated photonics for fabless companies and research institutions to be able to work with silicon nitride.
