Harness silicon nitride technology for your next project using an MPW service

Take advantage of ultra low-loss TriPleX™ waveguide technology in an easy-access, affordable way with a Multi Project Wafer (MPW) for silicon nitride integrated photonic circuits (PICs).

In an MPW run, we fabricate designs from several users on the same wafer of substrate. This approach controls costs and simplifies the design process, using standardized production steps and materials. The result is affordable access to leading PIC technology for low volume applications like academic research, R+D and prototyping.

visible light photonic integrated circuit for Multi Project Wafer (MPW) runs

Benefit from very low propagation loss across a very broad wavelength range with TriPleX silicon nitride waveguides.

Technology highlights

  • Low loss performance: <0.5 dB/cm @ 1.55µm with proprietary TriPleX™ silicon nitride waveguides
  • Excellent fiber coupling to waveguides with unique asymmetric double stripe cross-section
  • Easy and effective device layout with standardized building blocks

Who uses our MPW runs?

Our silicon nitride MPW is a great fit when you:

  • Are exploring integrated photonics’ possibilities
  • Just need a few chips for your design
  • Are investigating what technology fits your application
  • Are looking for the lowest entry costs

We were excited to access silicon nitride technology through the LioniX International MPW. Our application required really low-loss photonics in chip volumes appropriate to our early-stage technology. The design tools and building-blocks gave us and our partners an efficient way of doing the functional design and the packaging services saved us valuable time on our end.
