Observation of optical azimuthons

Minovich, Aliaksandr; Neshev, Dragomir; Desyatnikov, Anton S; Krolikowski, Wieslaw; Kivshar, Yuri


We observe experimentally optical azimuthons, a generic class of ring-shaped localised spiralling beams with azimuthal modulation, carrying phase dislocation in self-focusing nonlinear media. We observe three- and four-lobe azimuthons in 87Rb vapours and demonstrate their anomalous rotation controlled by the input phase distribution.
