Such stationary localized waves include previously predicted vortex- and dipole-mode vector solitons and also describe new higher-order vector solitons and necklace-type beams. We present the theoretical and experimental results of the structure, formation, and instability development of the quadrupole vector solitons.Keywords: Light propagation; Mathematical models; Optical waveguides; Vectors; Multipole spatial vector solitons; Solitons20012015-12-10
