Abstract
Optical solitons, ubiquitous and well-understood in low-dimensional systems, such as optical fibres, are in higher dimension a relatively new topic, as far as experiments are concerned. These entities – called Light Bullets (LBs) – where first observed in waveguide arrays [1] and exhibit dynamics, differing significantly from their low-dimensional counterparts. This difference is related to changed stability [2] and evolution [3] properties and direct coupling between spatial, temporal, and nonlinear evolution [4]. Here we investigate compound entities, namely spatially bound LB complexes with angular momentum, called Vortex LBs (VLBs) [5].
