Extended Data Fig. 7: Optical soliton propagation within arrays with k = 1 vortices.
From: Topological steering of light by nematic vortices and analogy to cosmic strings
a, Lightning-like optical soliton propagations after slightly shifting 1064 nm laser beam with respect to the array. b-e, Meandering solitonic light trajectories generated by 650 nm (b,d) and 1064 nm (c,e) laser beams. The trajectories are captured (upper) with and (lower) without illumination backlight of the microscope. Double yellow arrows mark orientations of crossed polarizers. All scale bars are 200 μm.
