The \u0026nbsp;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, which will be briefly reviewed in this talk.\u003C\/p\u003E\u003Cp\u003EThere is an all-important need in active devices capable of generating and amplifying coherent optical fields on the nanoscale analogous \u0026nbsp;to \u0026nbsp;lasers and \u0026nbsp;amplifiers of the conventional optics or transistors of microelectronics. Such an active device is the spaser (surface plasmon amplification by stimulated \u0026nbsp;emission of radiation), also called nanolaser. We will review theory extensive experiments on spasers. We will focus on two new theoretical ideas in the field of spasers: spaser with electric pumping via quantum wire and quantum-cascade graphene spaser. A recent breakthrough in ultrasensitive detection \u0026nbsp;of explosives using the spaser will be presented.\u003C\/p\u003E\u003Cp\u003EIn perspective, the spasers will have applications as ultrafast nanoamplifiers for petahertz processors, nanoscale sources of coherent and intense optical fields, ultra-bright nano-labels, and others.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ESpeaker Bio:\u003C\/strong\u003E\u003Cbr \/\u003EMark I. Stockman received his Ph.D. and D.Sc. degrees from the Institutes of the Russian Academy of Sciences. He is a professor of\u0026nbsp; physics \u0026nbsp;and \u0026nbsp;the\u0026nbsp; director \u0026nbsp;of \u0026nbsp;the \u0026nbsp;Center \u0026nbsp;for Nano-Optics (CeNO) at Georgia State University, Atlanta, GA, USA. He is a fellow of the American Physical Society (APS), Optical Society of America (OSA), and SPIE (the International Society for Optics and Photonics). He has served as a distinguished visiting professor at Ecole Normale Sup\u00e9rieure de Cachan (France) and as a visiting professor at Ecole Sup\u00e9rieure de Physique and de Chimie Industrielle (Paris, \u0026nbsp;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, in particular, ultrafast and nonlinear nanoscale optical phenomena. He is a \u0026nbsp;co-inventor \u0026nbsp;of the spaser (nanoplasmonic laser). He is the author of over 180 major research papers and has presented numerous plenary, keynote, and invited talks at major international \u0026nbsp;conferences. He has taught courses on nanoplasmonics and related topics at many major international meetings and scientific institutions in the United States, Canada, Europe, Asia, and Australia.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003E\u003Cbr \/\u003E\u003C\/strong\u003E\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Nanoplasmonics and Spaser"}],"uid":"27842","created_gmt":"2014-11-19 10:39:19","changed_gmt":"2017-04-13 21:21:03","author":"Ashlee Gardner","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2014-11-24T13:00:00-05:00","event_time_end":"2014-11-24T14:00:00-05:00","event_time_end_last":"2014-11-24T14:00:00-05:00","gmt_time_start":"2014-11-24 18:00:00","gmt_time_end":"2014-11-24 19:00:00","gmt_time_end_last":"2014-11-24 19:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"1255","name":"School of Electrical and Computer Engineering"}],"categories":[],"keywords":[],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[{"id":"78751","name":"Undergraduate students"},{"id":"78761","name":"Faculty\/Staff"},{"id":"174045","name":"Graduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003EHossein Taheri\u003C\/p\u003E\u003Cp\u003E\u003Ca href=\u0022mailto:h.taheri@gatech.edu\u0022\u003Eh.taheri@gatech.edu\u003C\/a\u003E\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
