Spatial solitons carrying phase singularities in nematic liquid crystals

Izdebskaya, Yana; Desyatnikov, Anton S; Assanto, Gaetano; Kivshar, Yuri

Description

We demonstrate self-trapped laser beams carrying optical vortices in nematic liquid crystals. We experimentally observe astigmatic transformations of vortex beams into spiralling dipole azimuthons accompanied by a nontrivial power-dependent charge-flipping of on-axis phase dislocations.
