The best of all worlds

Fraunhofer HHI’s PolyBoard enables the hybrid integration of active and passive optical functionalities into complex and highly functional photonic integrated circuits. Building blocks include tunable lasers at VIS and NIR wavelengths as well as thin film filters for polarization and wavelength handling. Furthermore, the micro-optical bench allows for the on-chip integration of optical isolators and circulators and nonlinear crystals for quantum technologies.

Fraunhofer HHI and ID Photonics offers a fully integrated 40GHz Bandwidth DP-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.

A portable PIC evaluation setup for fast and convenient prototype development

Fraunhofer HHI has developed a new PIC evaluation setup, named PIConnect, with 4 integrated laser drivers, 1 TEC, 8 current and 8 voltage sources. The PIC is assembled on the PIConnect PIC Assembly. The system enables parallel operation of the building blocks and, thus, convenient evaluation of PICs.

Components for 1Tb/s Transmission

Fraunhofer HHI provides 145 GHz single and 100 GHz balanced photodetector modules operating from the O- to the L-band. Application for the modules are, e.g., test and measurement and microwave photonics.

High-speed OWC links for vehicle-to-vehicle communication

Future applications like autonomous driving, smart cities and the networked broadband society demand for flexible solutions regarding communication. Decisive approaches to meet the challenging requirements are vehicle-to-vehicle communication, connected streetlights and the wireless last hop to the customer, also denoted as wireless to the home. For these purposes, economic point-to-point solutions are needed. Optical wireless links can provide robust communication at low-cost with high data rates, offloading traffic from commonly used directed radio technologies, e.g., millimeter wave, and thereby relieving the radio spectrum.

Fraunhofer HHI & IAF present a 100 Gbit/s THz wireless radio head with optical interface

The THz wireless radio head is a full duplex wireless communication prototype, operating at 300 GHz carrier frequency with 100 Gbit/s capacity over up to 1 km. The unit features a direct optical connection, which enables remote operation of the unit several kilometers away from the baseband equipment. The prototype was developed by Fraunhofer HHI, in cooperation with the Fraunhofer IAF.
