Polymer and Silicon Nitride Integration Platforms

Fraunhofer HHI offers hybrid photonic integrated circuits tailored towards their specific application from VIS to NIR.

The polymer and silicon nitride platforms of Fraunhofer HHI are specifically suitable for actives passives integration. Photonic building blocks including ring resonators, MMIs, AWGs, tunable gratings and phase shifters are available. The micro-optical bench allows for on-chip integration of polarization & wavelength handling elements as well as optical isolators, circulators, and nonlinear crystals for quantum technologies.

Robust sensor chips for medical technology and analytics

Photonic sensors based on silicon nitride are ideal for applications in medical technology and analytics due to their high sensitivity. Functionalized surfaces of the sensors enable the specific parallel detection of various molecules.

The Fraunhofer HHI sensor system solves the challenge of robust single-mode coupling with the help of well-matched optical couplers and a compact mechanical mount. This allows the advantages of integrated optical sensors to be utilized in on-site applications.

Live Demo of ML-assisted Capacity Adjustment of Open Terminals

We demonstrate autonomous link-capacity adjustment of open terminals, in optical metro aggregation networks, that relies on a transformer-based traffic forecaster to minimize over-provisioning.

We use the Data Sovereign Telemetry Framework of Fraunhofer HHI to monitor the aggregation switches as well as the performance of the open terminals once been reconfigured.
The live demonstration will be carried out on the large-scale photonics testbed of Fraunhofer HHI located in its premises in Berlin.
