Fraunhofer HHI is a Berlin-based applied research institute of the Fraunhofer Society specializing in optical communications, video coding, and imaging technologies. The institute conducts translated research connecting laboratory breakthroughs to industry adoption across telecommunications, media technology, and photonics supply chains. HHI has shaped standards, prototypes, and commercial products through partnerships with companies, universities, and international standardization bodies.

History

HHI traces intellectual roots to early 20th-century German telecommunications research and the legacy of institutes such as the Heinrich Hertz tradition and the Telefunken laboratories. During the Weimar Republic era and the Reichspost period, Berlin hosted foundational work that influenced later HHI activities. Post-World War II reconstruction aligned research with institutions like the Max Planck Society and the establishment of the Fraunhofer Society in 1949, leading to HHI’s formal integration within Fraunhofer. Throughout the Cold War, HHI interacted with entities including the Deutsche Bundespost and later with privatized successors such as Deutsche Telekom. In the 1990s and 2000s, HHI contributed to international efforts alongside the International Telecommunication Union, Moving Picture Experts Group, and Institute of Electrical and Electronics Engineers, influencing standards adopted by Apple Inc., Google LLC, Huawei, and Samsung Electronics. HHI’s timeline includes collaborations with research centers like the Technical University of Berlin, Technische Universität München, University of Stuttgart, and the Fraunhofer Heinrich Hertz Institute’s peers such as Fraunhofer IIS, Fraunhofer FOKUS, and Fraunhofer IKTS.

Research Areas

HHI’s research spans optical fiber systems, free-space optics, video compression, image processing, and quantum-safe communications. Work engages with technologies and organizations including W3C, MPEG, 3GPP, ITU-T, European Space Agency, and European Research Council projects. Key topics relate to standards and implementations affecting AV1, HEVC, VVC, JPEG, JPEG XL, and codecs used by firms like Netflix and Amazon (company). Optical research connects to developments in silicon photonics influenced by companies such as Intel, Broadcom Inc., and Xilinx. Quantum communication efforts reference experiments related to Quantum Key Distribution, links to projects with CERN, Oxford University, TU Delft, and initiatives funded by the European Union's Horizon 2020 and Horizon Europe programmes.

Organizational Structure and Funding

HHI operates under the governance model of the Fraunhofer Society with executive oversight comparable to other Fraunhofer institutes like Fraunhofer IIS and Fraunhofer ISE. Leadership interacts with municipal bodies including the Berlin Senate and federal ministries such as the Federal Ministry of Education and Research (Germany). Funding is a mix of competitive grants from sources including the German Research Foundation, contracts with corporations like Siemens, Ericsson, Nokia, and collaborative projects with consortia such as EUREKA and COST. HHI manages internal departments mirroring research clusters found at institutions like MIT, Stanford University, ETH Zurich, and Imperial College London to balance basic research, applied prototyping, and technology transfer to companies including Sony Corporation and Panasonic Corporation.

Facilities and Infrastructure

HHI’s facilities include fiber-optic testbeds, optical laboratories, high-performance computing clusters, and media labs comparable to those at Bell Labs and Fraunhofer IIS. Equipment and infrastructure support experiments with coherent transmission used by vendors such as Ciena, Infinera, and ADVA Optical Networking SE. Imaging and video labs host capture systems and codec testbeds used jointly with partners like BBC Research & Development, NHK, Rohde & Schwarz, and Fraunhofer IIS. Cleanrooms, cryogenic setups, and single-photon detectors align with resources at Max Planck Institute for the Science of Light and Humboldt University of Berlin. HHI maintains interoperability labs for standardization work alongside ETSI and 3GPP test suites.

Collaborations and Partnerships

HHI partners with multinational corporations, research universities, and standards bodies. Notable collaborators include Deutsche Telekom, Vodafone, Ericsson, Nokia, Huawei, Google Research, Microsoft Research, Apple Inc., Amazon Web Services, Netflix, BBC, NHK, ESA, CERN, TU Berlin, TU Delft, EPFL, ETH Zurich, Imperial College London, MIT, Stanford University, Max Planck Society, and Helmholtz Association. HHI contributes to consortia such as MPEG, ITU-T, IEEE, ETSI, IETF, W3C, Horizon 2020, and public–private partnerships involving BMW Group and Bosch.

Notable Projects and Innovations

HHI has driven innovations in video coding, optical transmission, and quantum communication. Contributions include research that influenced HEVC and VVC standards, codec experiments relevant to AV1 and JPEG XL, and prototypes for ultra-high-definition streaming used by Netflix and YouTube. Optical projects include demonstrations of terabit-per-second links aligned with technologies from Coherent Optics and companies like Ciena and Infinera. Quantum-safe communication trials connect to work at CERN, TU Delft, and University of Oxford and initiatives such as SECOQC. HHI-developed systems have been showcased at venues including Mobile World Congress, IBC (trade show), and CES and have been integrated into products by firms such as Bosch, Siemens, and Rohde & Schwarz.

Awards and Recognition

HHI researchers and teams have received accolades from organizations including the IEEE, VDE, European Commission, and national honors from the Federal Republic of Germany. Recognition includes contributions to prize-winning standards work acknowledged by MPEG committees and awards tied to collaborative projects funded by Horizon 2020 and industrial partners like Deutsche Telekom and Siemens. Individual scientists affiliated with HHI have been cited in awards and fellowships from Royal Society, Alexander von Humboldt Foundation, and professional societies including Optica (society) and ACM.
