Anderson localization is a regime in which diffusion is inhibited and waves (also electromagnetic waves) get localized. In a recent paper on Nat. Commun. we exploit adaptive optics to achieve focusing in disordered optical fibres in the Anderson regime.
Anderson localization means immoble waves in a disordered structure. We demonstrate that this paradigm is revolutionized when nonlinearity and nonlocality tak part to the game: Modes start to migrate when they “feel heat” generated by light absorbed along the fiber. See more on the journal article.
