Title:	Light dynamics in glass-vanadium dioxide nanocomposite waveguides with thermal nonlinearity
Author:	Kartashov, Yaroslav; Vysloukh, Victor A.
Abstract:	We address the propagation of laser beams in SiO2–VO2 nanocomposite waveguides with thermo-optical nonlinearity. We show that the large modifications of the absorption coefficient as well as notable changes of the refractive index of VO2 nanoparticles embedded into the SiO2 host media that accompany the semiconductor-to-metal phase transition may lead to optical limiting in the near-IR wave range
