标题： Light dynamics in glass-vanadium dioxide nanocomposite waveguides with thermal nonlinearity

摘要： 我们研究了在具有热光非线性的SiO2-VO2纳米复合波导中激光束的传播。 我们表明，伴随着半导体到金属相变，嵌入到SiO2基质介质中的VO2纳米颗粒的吸收系数的大幅变化以及折射率的显著变化可能导致近红外波段的光学限幅。 显示英文摘要

摘要： We address the propagation of laser beams in Si02-VO2 nanocomposite waveguides with thermo-optical nonlinearity. We show that the large modifications of the absorption coefficient as well as notable changes of 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-infrared wave range.
