Hybrid PICs

The best of all worlds

Fraunhofer HHI’s hybrid integration technology  PolyBoard combines polymer based PICs with InP platforms and enables complex photonic integrated circuits such as all-waveguide integrated THz receiver PIC for wireless communication and self-calibrated laser source for Telecom/Datacom, sensing and spectroscopy. The THz receiver PIC utilizes tunable lasers, modulator, and isolator to achieve on-chip injection locking and feeds the THz signal into the waveguide integrated photoconductive antenna. The self-calibrated laser source utilizes the micro-optical bench feature on PolyBoard which allows the precise wavelength read-out through thin film filters, etalons and photodiodes. Both complex PICs are founded through EU projects TERAWAY and TERAmeasure accordingly.

Performance Leading Reference Transmitter for Test & Measurement

Fraunhofer HHI and ID Photonics introducing the next generation Terabit Class IQ Reference Transmitter

The latest Test & Measurement Equipment launched by Fraunhofer HHI and ID Photonics is the DP-IQ Reference Transmitter . It is a fully integrated optical frontend instrument that converts differential electrical RF signals into various optical modulation formats (e.g. QPSK and m-QAM) using a high fidelity tuneable laser source followed by a high-bandwidth dual-polarization IQ Mach Zehnder modulator. It is an ideal match to convert signals generated by an Arbitrary Waveform Generator (AWG) into the optical domain. At a bandwidth of up to 60 GHz, this device provides unparalleled signal fidelity for research in next generation multi-level transmission formats even at high symbol rates beyond 100 GBaud/s in the Terabit/s single carrier regime. It is suitable as reference transmitter for receiver characterization or reference transmitter setups.

Machine Learning Pipeline for Network Automation

Machine Learning as a Service

The ML Pipeline  facilitates the streaming of telemetry data from network elements to a data lake, where it can be accessed by multiple telemetry data consumers. This allows network applications to utilize telemetry data in nearly real-time. The pipeline offers an ML inference host, through which various ML-assisted network functions can consume telemetry data.
