Anderson localization is a regime in which diffusion is inhibited
and waves (also electromagnetic waves) get localized. Here we exploit
adaptive optics to achieve focusing in disordered optical fibres
in the Anderson regime. By wavefront shaping and optimization, we
observe the generation of a propagation-invariant beam, where light
is trapped transversally by disorder, and show that Anderson localizations
can be also excited by extended speckled beams. We demonstrate that
disordered fibres allow a more efficient focusing action with respect
to standard fibres in a way independent of their length, because
of the propagation-invariant features and cooperative action of transverse
localizations.
