San Francisco, USA
The Fraunhofer Heinrich Hertz Institute 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 Photonics West 2020 Fraunhofer HHI presents the latest developments in Photonic Components and Fiber Optical Sensor Systems at Fraunhofer Booth 4545-26, from February 4-6 in San Francisco, USA.
Fraunhofer HHI presents sensory optical seals for real-time tamper protection of security-relevant hardware components like cryptographic communication chips. The optical seals, made of sensory ultra-thin glass slides, enclose the object to be protected. Autonomic alarm management is coupled with permanent monitoring of the integrity or change of state of seal.
An InP technology to cover a vast variety of monolithic or hybrid integration solutions
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 (40GHz), transmitters (20GHz) and (1dB/cm) passive components. Partners offer services for design work and packaging.
Polymer PICs now at 785nm and 1064nm
The PolyBoard platform of Fraunhofer HHI enables the hybrid integration of active and passive optical functionalities into complex and highly functional photonic integrated circuits (PICs). Recent developments include tunable lasers at wavelengths of 785 nm and 1064 nmfor applications in sensing and spectroscopy. Furthermore, PolyBoard’s micro-optical bench allows for the on-chip integration of optical isolators and circulators as an addition to the tunable lasers, as well as nonlinear crystals for quantum technologies.
Real-time layer thickness measurements
Terahertz radiation is increasingly employed for industrial process monitoring and material inspection. Coating layer thickness, the structure of polymers or imperfections in non-conductive materials can be determined.
Fraunhofer HHI presents a live demonstration of our continuous-wave system T-Sweeper. The measurement rate of up to 60 points per second allows for thickness measurements in real time, which makes the T-Sweeper a cost-efficient and robust alternative to pulsed THz systems.
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 test and measurement. For the application of microwave photonics dedicated high-power photodetector modules are presented.
