Best of all worlds

Fraunhofer HHI’s PolyBoard platform enables the hybrid integration of complex and highly functional photonic integrated circuits (PICs) including active and passive optical functionalities. Recently, on-chip isolators with an isolation ratio of 20 dB over a bandwidth of 150 nm have been developed, and are included as new optical functionalities of the platform. They utilize on-chip free-space sections, which also allow for the integration of nonlinear optical crystals to target applications in quantum technologies.

Furthermore, in the framework of the BMBF-funded PolyPhotonics project, Fraunhofer HHI presents its latest PIC developments, such as 10G tunable transceivers and fiber Bragg interrogator units for applications in Telecom / Datacom as well as sensing and spectroscopy.

Fraunhofer HHI proudly announces the unlimited access to C and O Band Mach-Zehnder Modulators for more than 64 Gbaud using its mature and efficient Indium Phosphide technology.

Optionally, these modulators are available in an IQ configuration or are monolithically integrated with a DFB laser. Adding Fraunhofer HHI’s expertise in driver co-design for ultra-low power consumption results in e.g. 2.3 pJ/bit for 128 Gbit/s.

Components for 1Tb/s Transmission

Fraunhofer HHI provides 100 GHz single and balanced photodetector modules operating from the O to the L band. The intended application for the modules is test and measurement.

Make your light smarter

Fraunhofer HHI presents the second generation Gigabit Visible Light Communication (VLC) modules for wireless internet access via light. Outstanding features are the smaller form factor, lower energy consumption, enhanced data rates and multi-user access. A standard Ethernet interface allows easy network integration. The new modules are immediately available for industrial prototyping and field tests.

Coherent optical receiver with up to 100 GHz analog electrical bandwidth in a 19‘‘-chassis

The device features four optical extender heads for direct connection to high-bandwidth A-to-D-converters or oscilloscopes. This ensures a high quality of the 100 GHz electrical signals.

Compact optical transceiver plug-in card to demonstrate high-bitrate data transmission

The plug-in card allows for flexible generation and detection of optical data signals, such as 32-GBd PDM-16QAM. The plug-in card is an ideal add-on to Fraunhofer HHI’s highly flexible FPGA-based development and demonstration platform for signal processing algorithms and real-time data transmission.

The generic InP integration platform at Fraunhofer HHI continues to be extended. Latest upgrades include components for handling of optical polarization as well as general performance upgrades. Fraunhofer HHI offers an InP platform that integrates receivers (40 GHz), transmitters (20 GHz) and (1 dB/cm) passive components. Partners offer services for design work and packaging.

The terahertz (THz) frequency range is relevant for wireless transmission of high data rates in 5G mobile networks as well as for non-destructive testing and monitoring of industrial production processes. Fraunhofer HHI presents fiber-coupled transmitters, coherent receivers and high-resolution THz measuring systems. With a bandwidth above 3 THz, the optoelectronic approach of Fraunhofer HHI has distinct advantages over mere electronic solutions.
