Biography
Vasily N. Astratov is a professor in the Department of Physics and Optical Science at the University of North Carolina-Charlotte. He received his M.S. from the St. Petersburg State University, Russia, in 1981, and received his Ph.D. degree from the A.F. Ioffe Physical-Technical Institute, St. Petersburg, in 1986. At this institution he had accomplished a career as a research scientist, rising through the ranks from staff member (1981-1992), group leader (1992-1997), to senior member of staff in 1997. In his group at Ioffe Institute he pioneered studies of synthetic opals as novel 3D self-assembled photonic crystals for visible light. In 1997-2001 he worked as a postdoctoral scholar at the University of Sheffield where he developed novel surface coupling techniques for studying photonic crystal waveguides and semiconductor microcavities. He joined UNC-Charlotte in 2002. He was a topical editor for the journal Optics Express in 2005-2011 and an editor and co-editor for two Focus Issues of this journal. He has served as a technical committee member for major international conferences including CLEO/QELS 2006-07 and 2012-13, ICTON 2009, and OECC/ACOFT 2008. He is a recipient of a number of awards including International Visitor Award in France by Triangle de la Physique in 2011, Senior Visiting EPSRC Fellow Award in the UK in 2006, Award of the Exchange Program adopted between Royal Society and Russian Academy of Sciences in 1996, and the Award in the Annual Competition from A.F. Ioffe Physical-Technical Institute in 1985. During his career he has published more than 130 technical publications which have been cited more than 2400 times. His Hirsch index is h=23. He is an author and coauthor of 10 patents. His current research spans a broad range of optical effects in mesoscale photonic structures including photonic nanojets, unusual sensor capabilities, resonant light pressure and optical super-resolution effects.
