Title: Surface nanoscale axial photonics
Abstract: Surface Nanoscale Axial Photonics (SNAP) platform, introduced in 2011, enables fabrication of nanoscale-shallow microresonator structures at the surface of an optical fiber with subangstrom precision. It employs whispering gallery modes circulating and slowly propagating along the fiber. First, I review the SNAP theory, which resembles one-dimensional quantum mechanics, and its fabrication methods. Next, I discuss our recent experimental and theoretical results on interplaying slow and tunnelling light, resonant tunnelling, and nonlinear SNAP. Finally, I switch to microfluidics and describe our recent experiments where temporary and permanent SNAP microresonators are induced by water in silica microcapillaries.
Bio: Michael (Misha) Sumetsky graduated from the Saint-Petersburg State University, Russia, and has Ph.D. (1979) and D.Sc. (1989) degrees from the same University. He worked at the Physics Department of Saint-Petersburg University of Telecommunications (Russia) from 1979 till 1995 when he joined Bell Laboratories (USA). In 2001, Dr Sumetsky continued his research at OFS Labs after transition of the Optical Fiber Research Department of Bell Labs into the OFS Labs of the Furukawa Electric Company. In 2013, he joined Aston University (UK) as a Professor of Photonics.
