Photonic Integrated Circuits (PICs) based on Silicon-Nitride (Si3N4) technology find use in many applications. Especially our TriPleXwaveguide platform is used in many applications over a broad range of markets. Our customers base ranges over all these markets.

With our vertically integrated approach of designing, manufacturing and assembling the customized PIC, we support our customers in matching the PIC technology for their needs, both in specifications and in volume.

Besides our customized work, LioniX International is developing PIC technology to highlight a number of applications that either show the advantages of using PIC technology very well, or that benefit from using our technology.

In the overview below you find a range of applications of silicon nitride PICs.

Microwave Photonics

The hybrid microwave photonics platform enables high-frequency signal processing and provides significant benefits over conventional free-space optics systems and RF-circuitry. The unique properties of our proprietary integrated photonics platform are imperative in beamforming applications in 5G wireless mobile networks, Satellite communication, Aerospace communication and Quantum processing.


Being transparent over a long wavelength range, silicon-nitride based TriPleXTM photonic integrated circuits are applied in many applications outside the communication band. In the medical market the application of Optical Coherence Tomography is gaining more and more interest. In ophthalmology OCT …

Tunable laser

Our hybrid assembly approach to silicon-nitride based photonic integrated circuits is applied in our narrow-linewidth tunable laser. This laser has an ultra-narrow linewidth and is tunable over a the whole C-band. The combination of wavelength accuracy with tunability makes …
