WUHAN, China (November 14, 2017) - Wuhan Optoelectronics Forum No. 133 was successfully held in Auditorium A101 at Wuhan National Laboratory for Optoelectronics (WNLO) in the morning of November 14. Prof. Michael Sumetsky from Aston University delivered an exciting talk entitled Recent Progress in Surface Nanoscale Axial Photonics. Dr. XueWen Shu, from Optoelectronic Devices and Integration Division of WNLO chaired the forum. Prof. Xinliang Zhang, Deputy Director of WNLO, awarded Prof. Michael Sumetsky the forum medal.
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.
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).
