OPIE 2024

APR 2024

24 - 26

Yokohama, Japan

The Fraunhofer Heinrich-Hertz-Institut (HHI) is a world leader in the development for mobile and optical communication networks and systems as well as processing and coding of video signals. Together with international partners from research and industry, Fraunhofer HHI works in the whole spectrum of digital infrastructure – from fundamental research to the development of prototypes and solutions.

At OPIE 2024 Fraunhofer HHI presents the latest developments in Photonic Components, Networks and Systems at Booth G02 from April 24-26 in Yokohama, Japan.

Hybrid PICs

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.

High-Speed Photodetector Modules

Components for 1Tb/s Transmission and Microwave Photonics

Fraunhofer HHI provides single and balanced photodetector modules with a bandwidth up to 145 GHz operating from the O- to the L-band. The intended application for the modules is high-speed test and measurement. Our novel module design provides higher and smother RF performance and improved reliability.

100 GHz Coherent Receiver Frontend with Optical Extender Heads

Fraunhofer offers a fully integrated 100 GHz bandwidth coherent receiver frontend with optical extender heads

To cope with the continuously growing demand for bandwidth over multiple wavelength bands in telecom and datacom applications, Fraunhofer HHI researchers developed a Coherent Receiver Frontend (CRF), offering 100 GHz bandwidth detection with polarization- and phase-diversity over S+C+L-band. Its unique features are optical extender heads with robust 1mm RF ruggedized connectors enabling high signal integrity, robust testing & measurement performance and convenient handling & operation for our customers.

Integrated Coherent Optical Receiver

Fraunhofer HHI and ID Photonics offer a fully integrated Coherent Optical Reference Receiver with up to 60 GHz

The latest test & measurement equipment launched by Fraunhofer HHI and ID Photonics is the fully integrated Coherent Optical Reference Receiver. It comprises a high-bandwidth coherent receiver with transimpedance amplifiers to convert optical data signals with various modulation formats (e.g. QPSK and m-QAM) into electrical RF baseband signals with an o/e bandwidth up to 60 GHz. Its unique features are a high fidelity tuneable C-band laser source and a fully integrated Coherent Optical Receiver, allowing operation at symbol rates beyond 120 GBaud, enabling transmission capacities in the Terabit/s single carrier regime.

Photonic Transmitters and Receivers for THz Communications from 100 GHz to 1 THz

High-data rate wireless links at (sub-)THz carrier frequencies

Based on its mature InP technology, Fraunhofer HHI develops photonic components and systems for high-data rate wireless terahertz communications. These components allow for seamless integration into state-of-the-art fiber-based communication systems. Thus, complex modulation formats, such as 32QAM, 64QAM and QPSK, can be used. In a recent publication, we showed up to 160 Gbit/s at 300 GHz carrier frequency using 32QAM (Nellen et al., JLT 40(13), 2022).

Test and Measurement for 6G and beyond

Broadband spectral coverage from 100 GHz to 4.5 THz

The photonic terahertz components and systems developed by Fraunhofer HHI are well suited for test and measurement applications for 6G and beyond. In contrast to electronic mixer circuits, with a single system the photonic approach allows for broadband access to frequencies between 100 GHz and 4.5 THz. Since the specific frequency bands of future wireless communication channels are still a topic of debate, our approach helps to reduce this uncertainty by providing access to a broad spectral range.

LiFi for Mobility and Transport

Connectivity at the Speed of Light

Fraunhofer HHI is exhibiting a new optical wireless communication system for mobility and transport applications. The wide 120° coverage enables robust high-speed data communication with a high degree of mobility. The light-based LiFi system can be used in industrial environments and is especially well suited for vehicle to vehicle communication. Vehicles can communicate with a stable connection at high speeds while moving. Using LiFi instead of radio-based systems enables a robust hacking-, jamming-, and interference-free transmission.
