Prof. Dmitry Skryabin
Department of Physics
University of Bath, UK
Prof. Dmitry Vladimirovich Skryabin graduated from Physics
Department of St. Petersburg State University; received Ph. D. degree
from the University of Strathclyde in Glasgow, Scotland (with
Professor William Firth). Since 2001, he is an assistant, then an
associate and from 2012 is a full Professor of Physics at the University of Bath, England.
He has recently been part-time affiliated with the ITMO University in St. Petersburg and
Russian Quantum Center in Skolkovo. Prof. Skryabin is a Fellow of the Optical Society
of America and of the London’s Institute of Physics. He is a recipient of the 2009
Maxwell prize for his work on supercontinuum generation in optical fibres. His primary
areas of interest are nonlinear photonics and solitons.
I will discuss recent results that reveal new features of the frequency combs in ring
resonators described by the Lugiato-Lefever model. These features are associated with a
periodicity of the boundary conditions in a spatial coordinate and produce a host of new
effects that are appearing in a recent wave of experimental results in fibre loop and
micro-ring resonators. I will describe how periodicity of the problem introduces
coexisting nonlinear resonances and coexisting solitons. Then, I will introduce higherorder
dispersion into the problem and elaborate on the effects associated with the
interaction of the solitonic Cherenkov radiation with its parent soliton, after the radiation
makes a complete round trip around the resonator. I will present results on how the
Raman and 2nd harmonic generation effects influence frequency comb generation.
