The aim of research and development activities at the
Fraunhofer Institute for Telecommunications, Heinrich-Hertz-Institut (FhG/HHI)
is to further develop the principles of information technology and to demonstrate, in partnership with industry, new applications for new products. The R&D projects are focused on some of the most challenging areas of today's information technology: Photonic networks and components, mobile broadband systems and electronic imaging technology for multimedia.
The Heinrich-Hertz-Institut is part of the Fraunhofer-Gesellschaft, an autonomous organization with a decentralized organizational structure, which currently maintains 58 research institutes throughout Germany. The research institutes operate from different locations in Germany, where they carry out their respective work in close partnership with industry.
The core competence of the Heinrich-Hertz-Institut (FhG/HHI) is in the areas of photonic networks, mobile broadband systems, and electronic imaging technology for multimedia. In its three main working areas the FhG/HHI is a valued partner in national and international co-operative research and development projects. The FhG/HHI has 270 employees and app. 80 students as R&D assistants. Nearly half of FhG/HHI's staff is working in the Photonic Networks area. The objective of research in this area is to make substantial contributions to the development of photonic networks and advanced photonic components.
FhG/HHI has been involved in optical transmission research from the very beginning. Along with this expertise a full range of design and measurement capabilities exists in photonic networks with the emphasis on the physical and operational layers. Longstanding expertise exists in InP based photonic components and photonic integrated circuits (PICs), complemented by silica on silicon and polymer devices and PLCs. FhG/HHI possesses a full fabrication line for these components embracing epitaxy (MOVPE, MBE, MOMBE), electron beam lithography mask making photolithography, dry etching, deposition and coating, mounting and assembly, as well as material analysis, test and characterization. Although the fab facility is primarily used for research and development prototyping, components can be produced in small scale series on wafer/chip-level for industrial partners.
In the past FhG/HHI had been involved in several ESPRIT, RACE and IST programmes. Within ACTS FhG/HHI has participated in BLISS, METON, REPEAT, DEMON, HIGHWAY, PHOTON and MOEMS, within IST participated in: OPTIMIST, OBANET, DRIVE, ATTEST, VIRTUE, SAMBITS, MASCOT and TOPRATE.
The participation in the HECTO project is carried out within two departments: Optical
Networks Department (ON) and Integration Technology Department (IT). The ON will mainly
do the necessary test and measurement activities for evaluation of the developed receiver
modules and its subcomponents in system experiments, and provide support for other project partners regarding transmitter test and specification activities. The IT focuses on the development of the Indiumphosphide-based receiver chips. FhG/HHI will act as work package leader of WP3 coordinating the receiver development including development of detector, amplifier, demultiplexer and clock and data recovery circuits.
