Prof. Hartmus Roskos
Title: Coherent and incoherent detection of THz radiation with field-effect transistors
Biography: Hartmut Roskos is Professor of Physics at Johann Wolfgang Goethe-University, Frankfurt am Main, Germany. He studied Physics at the Technical Universities of Karlsruhe and Munich, receiving the PhD degree from the latter in 1989. He then worked at AT&T Bell Laboratories, Holmdel, USA, where THz phenomena became the focus of his research. He joined the Institute of Semiconductor Electronics of RWTH Aachen in 1991. After receiving the Habilitation degree with a thesis on Coherent Phenomena in Solid-State Physics Investigated by THz Spectroscopy, he became a Full Professor at Goethe-University in 1997. He spent sabbaticals at UCSB in 2005 and at the University of Rochester in 2014, and was an Invited Guest Professor at Osaka University’s Institute of Laser Engineering during the winter semester 2009/2010. In 2009, OC Oerlikon AG awarded his group jointly with the Ferdinand-Braun-Institute (FBH) in Berlin a 5-year endowed professorship which led to the establishment of a permanent JointLab for THz Photonics of FBH and Goethe University now chaired by Prof. Dr. Viktor Krozer. Prof. Roskos is a Topical Editors of Optics Letters. His research areas include ultrafast optical and THz spectroscopy, s-SNOM nanoscopy, THz device physics, and applications of THz radiation.
