Abstract

From 1976 to 2000 Hans Melchior was Professor for Electronics at the Swiss Federal Institute of Technology in Zurich, Switzerland. Initially with the Institutes of Electronics and Applied Physics, in 1986 he co-founded and joined the Institute of Quantum Electronics in the Department of Physics. His Laboratory of Micro- and Optoelectronics was devoted to three-five compound semiconductor research. Activities included opto-electronic waveguide components for fiber optical communication, including semiconductor lasers, optical amplifiers, electro-optic switches. All-optical signal processing devices for optical signal regeneration, wavelength conversion and with optical demultiplexing capabilities up to 160 Gbit/s were a speciality. Achievements also included an indium phosphide heterobipolar transistor technology capable of optical transmitter and receiver circuits up to 10 and 40 Gbit/s.
