Photonics for on-site sensor systems

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.

400G Coherent Optical Frontend

Fraunhofer presents a compact 400G I/Q transmitter and coherent receiver for high-bitrate transmission experiments

The 400G Coherent Optical Frontend is a compact optical transceiver to demonstrate high-bitrate data transmission. The transceiver allows for flexible generation and detection of optical data signals up to 64 GBaud. This corresponds to 400 Gbit/s using PDM-16QAM modulation. Several transceivers can be combined in one chassis to realize a multi-channel system, e.g. for space-division multiplexing.

Data Sovereign Telemetry Framework

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.
