ECE Colloquium with Mark Stockman

Quantum Nanoplasmonics and Spaser With Mark I. Stockman Ludwig Maximilian University - Munich, Germany Max Planck Institute for Quantum Optics - Garching, Germany Department of Physics and Astronomy, Georgia State University Refreshments will be served outside Room 339 at 3:45 p.m. Faculty Host: Luca Dal Negro Abstract: Nanoplasmonics deals with collective electron excitations at the surfaces of metal nanostructures, called surface plasmons. The surface plasmons localize and nano-concentrate optical energy creating highly enhanced local fields. Nanoplasmonics has numerous applications in science, technology, biomedicine, environmental monitoring, and defense. There is an all-important need in active devices capable of generating and amplifying coherent optical fields on the nanoscale analogous to lasers and amplifiers of the conventional optics or transistors of microelectronics. Such an active device is the spaser (surface plasmon amplification by stimulated emission of radiation). We will present quantum theory of spaser as an ultrafast quantum generator and amplifier of nanoplasmonic fields. We will review extensive experiments on spasers. In perspective, the spasers will have applications as ultrafast nanoamplifiers for petahertz processors, nanoscale sources of coherent and intense optical fields, non-saturable nano-labels, and others. About the Speaker: Mark I. Stockman is a Professor of Physics at the Department of Physics and Astronomy, Georgia State University (Atlanta, Ga.). He is a Fellow of the American Physical Society, Optical Society of America (OSA), and the International Society for Optoelectronic Engineering (SPIE). He received his Ph.D. and D.Sc. degrees from institutes of the Russian Academy of Sciences. He has served as a Visiting Professor at Ecole Normale Superieure de Cachan (France) and Ecole Superieure de Physique and de Chimie Industrielle (Paris, France), and also as a Guest Professor at University of Stuttgart (Germany), Max Plank Institute for Quantum Optics (Garching, Germany), and Ludwig Maximilian University (Munich, Germany). A major direction of his research is theoretical nanoplasmonics, especially theory of ultrafast and nonlinear nanoscale optical phenomena. He is a co-inventor of spaser (plasmonic nanolaser). He is an author of over 170 major research papers and has presented numerous plenary, keynote, and invited talks at major international conferences. He taught short courses on nanoplasmonics and related topics at many major international meetings and scientific institutions in the United States, Canada, Europe, Asia, and Australia.
