“Mesophotonics: Novel Optical Effects in Coupled
Microspheres”
ABSTRACT
This talk is devoted to “mesophotonics” – novel area of photonics dealing with the optical properties of mesoscopic
systems of coupled cavities with dimensions in the order of several wavelengths. The focus of this presentation is on
developing new concepts related to light transport in systems of coupled microspheres including photonic nanojetinduced modes, percolation of whispering gallery modes and the role of structural disorder and dimensionality. At the
device level, these studies stimulate developing designs where coupled cavities are applied to tight focusing microprobes, sensors, and compact spectrometers.
BIOSKETCH
Vasily Astratov is an associate professor in the Department of Physics and Optical Science at the University of North
Carolina-Charlotte, joining the faculty in 2002. He received his Ph.D. degree from the A.F. Ioffe Physical-Technical
Institute, St. Petersburg, Russia, in 1986. In 1993-1997 he headed a research group at the Ioffe Institute where he
pioneered studies of synthetic opals as new 3D photonic crystal structures. In 1997-2001 he has been a postdoctoral
scholar at the University of Sheffield, UK, working on semiconductor microcavities, photonic crystals, and opals. He
is a topical editor for the journal Optics Express since 2005. In 2007 he organized and edited a Focus Issue of Optics
Express devoted to Physics and Applications of Microresonators. He has served as a technical committee member for
CLEO/QELS 2006-07, Special session on Microresonators and Photonic Molecules at ICTON 2007-08, and OECC/
ACOFT 08. He has been a member of the international DFG panel on photonic crystals in Germany in 2000-05 and a
member of the NSF panels on photonic devices and technology in 2004-08. He is a recipient of a number of awards
including Senior Visiting EPSRC Fellow Award in the UK in 2006 and Award of the Exchange Program adopted
between Royal Society and Russian Academy of Sciences in 1996. He is a co-author of over 90 publications and 9
patents which have been cited over 1500 times. His current research is devoted to synthesis, optical characterization,
and modeling of mesoscale photonics structures.
