Abstract

Localization of coherent propagating waves has been extensively studied in homogeneous random media. However, significantly less attention has been given to wave localization in inhomogeneous systems, where the standard picture of Anderson localization does not apply. By fabricating photonic lattices with inhomogeneous disorder modeled by heavy-tailed distributions, namely Lévy α-stable distributions, and measuring the output light intensity profiles, we show that the spatial localization of light is asymmetric concerning the excitation site and is described by a stretched exponential function. The results contrast with the well-known exponential localization in Anderson localization phenomena.
