Example of an Arrayed Waveguide Grating (AWG) based on silicon nitride waveguides.

Fraunhofer IPMS develops devices and photonic integrated circuits based on silicon nitride waveguides. By using tailor-made technologies, Fraunhofer IPMS offers the possibility to monolithically integrate waveguides with CMOS devices and to design them with low losses.

Unique opportunities arise from the possibility to combine silicon nitride waveguides with liquid crystal waveguides, where a specific electrode configuration can lead to new programmable devices for different applications.

Fraunhofer IPMS has expertise in the design, fabrication and characterisation of waveguide devices and photonic integrated circuits, which are used e.g. as wavelength filters, switches, multiplexers etc. in optical communication networks, in spectroscopy and as transducer elements in optical sensing and biosensing (see micro ring resonator biosensor).

The waveguides are fabricated on 200 mm wafers in the Fraunhofer IPMS clean room. Their characterisation is carried out in special laboratory setups at Fraunhofer IPMS and Fraunhofer MEOS.
