Biography:

Michael (Misha) Sumetsky, Professor of Photonics, Aston Institute of Photonic Technologies, Aston University, OSA fellow, Royal Society Wolfson Merit Award Holder. He graduated from the Saint-Petersburg State University, Russia, and received Ph.D. and D.Sc. degrees from the same University. He worked at the Physics Department of Saint-Petersburg University of Telecommunications (Russia) till 1995 when he joined Bell Laboratories (USA). In 2001, he 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. He joined the Aston Institute for Photonics Technologies at the end of 2013 where he holds a full professor position.

His research interests are optics of microresonators and nanophotonics. To this end, he has invented and demonstrated several optical micro-resonators, and explained the nature of transmission losses in nanofibers. He has first proposed SNAP (Surface Nanoscale Axial Photonics) and demonstrated fully reconfigurable SNAP circuits with subangstrom precision. He holds 25 patents, over 200 papers in journals and conference proceedings and ~50 invited talks at international conferences and workshops. He is the member of the editorial board of several journals, including Optics Letters (OSA), Optics (MDPI), and Journal of Optical Physics (Hindawi).

报告摘要：

表面纳米轴向光子（SNAP）技术是一种基于光纤表面制造光子回路的新型平台，其表征可达亚埃米精度。其制作方法通常采用CO2激光束曝光法，在加工过程中使光纤局部退火并释放光纤中的应力，该方法制作的微谐振器具有纳米尺度的有效直径变化。本次报告主要概述SNAP技术及其应用，并着重介绍我们在2016-2017年期间获得的最新成果。特别地，将介绍基于毛细管纤维的SNAP技术在微流体中的理论及实验结果，SNAP微瓶谐振器中频率梳的产生及SNAP微瓶谐振器的光力学理论。

Abstract:

Surface Nanoscale Axial Photonics (SNAP) is a novel platform for fabrication of photonic circuits at the optical fiber surface and their characterization with unprecedented sub-angstrom precision. Their fabrication usually consists of exposures to a CO2 laser beam, which locally anneals the optical fiber and releases tension frozen into the fiber during manufacture. This results in fabrication of microresonators with an effective radius variation on the order of nanometers. In this presentation I overview the ideas and applications of SNAP technology and concentrate on our recent findings obtained in 2016-2017. In particular, I will describe our theoretical and experimental results on SNAP at the capillary fiber for applications in microfluidics, frequency comb generation in SNAP bottle resonators, and optomechanics of SNAP bottle resonators.
