Hybrid PICs

PolyBoard- and SiN-platforms

The Fraunhofer HHI platforms enable the hybrid integration of active and passive optical components in photonic integrated circuits (PICs) in the visible and infrared wavelength range. The micro-optical-bench of the PolyBoard platform facilitates PICs with spectral filters, optical isolators and circulators, as well as nonlinear crystals for applications in quantum optics, among others. The silicon-nitride-platform features highly integrated optical gratings, switches and ring resonators for communications, sensing and medical technology.

Photonic Components for THz Communications

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. For example, our cw-THz system T-Sweeper offers up to 50 spectra / s with >4 THz bandwidth or up to 500 spectra / s with 200 GHz bandwidth. 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.

Fraunhofer HHI presents a modular LiFi system that can also be connected via fiber-to-the-room for the first time. The optical access points can be connected to a passive optical network (XGS-PON) and thus enable high data rates and a low-latency connection. In addition, the high capacity of the PON makes it a sustainable and future-proof building network.
