Terahertz Sensors and Systems
The Terahertz Sensors and Systems Group (THZ) applies its telecom matured InP-technology for developing photomixers and photoconductive antennas which convert optical signals in the 1.5 µm wavelength range into THz radiation and vice versa.
Head of Group: Prof. Dr. rer. nat. Björn Globisch
IC Design
The IC Design Group (ICD) develops high-speed IC for optical communications and provides high-frequency measurements and electromagnetic analysis.
Contact: Dr. Jung Han Choi
Diffractive Optical Elements
Our portfolio of elements, mainly implemented in quartz glass, silica and silicon, covers the wavelength range from the DUV to the IR region.
Contact: Dipl.-Phys. Margit Ferstl
Epitaxy
The Epitaxy Group (EPI) manufactures and develops InP-based wafers for optical and opto-electronic components.
Head of Group: Dr. rer. nat. Christoph Hums
Processing
The Fraunhofer HHI has industry standard cleanroom facilities of ISO classes 4 to 6 (former classes 10 to 1000). The complete process line starts with ebeam lithography for mask fabrication and direct writing and includes all technology steps up to final electroplating and AuSn-sputtering for contact-pads or flip-chip-bumps.
Head of Group: Dr. rer. nat. Kristijan Posilovic
Backend & Packaging
The Backend and Packaging Group (BaP) separates the photonic components developed at Fraunhofer HHI into chips, carries out optical coating processes and assembles the devices into demonstration modules and submounts.
Head of Group: Dipl.-Ing. (FH) Greta Ropers
