Carl Zeiss Visiting Professor Gaetano Assanto

Professor Dr. Gaetano Assanto vom Nonlinear Optics and OptoElectronics Lab der Universität Roma Tre hält sich im Rahmen einer Carl-Zeiss-Gastprofessur mehrere Wochen im Zeitraum Mai bis Juli und August bis September 2010 an der Physikalisch-Astronomischen Fakultät der Friedrich-SchillerAssanto_Gaetano_web100 Universität Jena auf. Während seines Aufenthaltes hält Professor Assanto eine Vorlesungsreihe zum Thema "Moderne Entwicklungen auf dem Gebiet optischer Solitonen". Die zweite Vorlesung finden am Montag, den 30. August 2010, statt.



Gaetano Assanto received his M.Sc. in Electronic Engingeering at the University of Palermo in 1981. Having finished his PhD in Electr. & Comm. Engg. he joined the Center of Electronic Research in Sicily as a Research Engineer in 1987. From 1988 to 1990 he was Research Associate at the Optical Sciences Center at the University of Arizona, then, from 1990 to 1992, Senior Research Scientist at CREOL. Since November 1992 he is professor of Optoelectronics at the University of Rome "Roma Tre". His current interests are in nonlinear effects (parametric, Kerr-like, reorientational, thermo-optic) for all-optical signal processing and light localization, as well as Ge-on-Si heterostructures and optoelectronics for near-infrared detection. Professor Assanto is a Fellow of the Optical Society of America (OSA), senior member and Distinguished Lecturer of the IEEE Photonics Society, member of the International Society for Optical Engineering (SPIE), the National Institute for Nuclear Physics (INFN), the European Physical Society and of the Executive Committee of the Italian IEEE-LEOS Chapter. In addition, he is member of the editorial board of OSA Optics Letters, IEEE Photonics Journal, Journal of Nonlinear Optical Physics and Materials, Hindawi Research Letters in Optics, Laser Physics Review and Photonics Letters of Poland.
