The temporal fluctuation of the inverse participation ratio for localized field modes in three-dimensional percolation system

Abstract

We investigate the structure of the  optical field radiated by the disordered optical nano-emitters randomly incorporated  in three-dimensional cluster of a percolation material. Our numerical studies shown that the temporal variations of the inverse participation ratio (IPR) allow analyzing the extended and localized field structures over a long time range. The properties of IPR and the dynamics of the lasing emitters allow to find the characteristic time scales when the localization of the field in a general three-dimensional disordered system occurs. The studied effect opens new perspectives to control the optical fields localization in modern optical nano-technologies.
