We report the first demonstration of PT-symmetry and its breaking in a system of two directly-coupled on-chip whispering-gallery-mode microresonators[1]. We observed strong nonreciprocity due to strong-field localization and enhanced nonlinearity in the broken PT-symmetry phase.
Whispering-Gallery-Mode(WGM) resonators can significantly enhance light-matter interaction. We discuss self-pulsing behaviors in WGM microlasers due to nonlinear optical losses introduced by excited state absorption. Ultra-sensitive self-referencing detection of nanoparticles using WGM microlasers is demonstrated.
The properties of the fog layer, such as the vertical thickness, optical thickness and the visibility, are of significant importance in the aspect of researching the fog dissipation and detection. These parameters have been successfully retrieved in this paper, mainly using MODIS data source in Yangtze River Delta, on the basis of the radiation transfer theory and reasonably simplifying the radiation...
