报告摘要

Solution of several exciting problems of modern photonics (e.g., creation of practical miniature slow light devices) is challenged by insufficient fabrication precision and attenuation of light. Here I review the Surface Nanoscale Axial Photonics (SNAP) platform, which allows to create photonic circuits at the fiber surface with unprecedented sub-angstrom precision and ultralow loss. The propagation of light in SNAP circuits is described by one-dimensional Schrödinger equation and imitates the basic phenomena of quantum mechanics (quantum wells, tunnelling, turning points, etc.) The applications of SNAP range from miniature optical delay lines, buffers and frequency comb generators to microfluidics.

报告人简介：Michael (Misha) Sumetsky graduated from the Saint-Petersburg State University, Russia, and has Ph.D. and D.Sc. 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 the Aston Institute of Photonics Technologies as a Professor of Photonics. Prof. Sumetsky is a Fellow of the Optical Society of America and a holder of Royal Society Wolfson Research Merit Award. He has more than 200 publications and more than 20 patents in optics and quantum mechanics. His present research interests are in optics of microresonators, micro/nanofibers, and nanophotonics.
