HEINRICH-HERTZ-INSTITUT für Nachrichtentechnik GmbH (HHI), Berlin Prof. C. Baack, Dr. N. Grote (Photonics Div.)

The HHI is a research center owned by the Federal Government and the state of Berlin as member of the Wissenschaftsgemeinschaft Gottfried Wilhelm Leibniz (WGL). Its goal is to pursue application-oriented research and development to help commercial enterprises compete in technological areas, having its core competence in photonic networks and related devices, mobile broadband systems and electronic imaging technology for multimedia.

Closely collaborating with HHI's systems groups, photonic devices are primarily developed on the basis of InP semiconductor materials, but also on silica and optical polymers. The R&D work ranges from basic research to the development of prototype devices and low-volume production of high-end devices, with a total of some 75 people being engaged in this field. A complete line of R&D equipment, including e. g. the epitaxial techniques MOVPE and (MO)MBE, and e-beam lithography, is available enabling the realization of a wide spectrum of advanced optoelectronic/photonic devices. Various types of lasers, very high speed photodetectors and -receivers, modulators, wavelength converters, optical demultiplexers, components for optical regeneration, and others, have been under development, many of them incorporating nanoscale QW layers. Special emphasis is on the monolithic integration of such devices to result in optoelectronic integrated circuits, e. g. optical transceivers.
