Extended Data Fig. 5: Optical soliton steering by topological vortex dimers.
From: Topological steering of light by nematic vortices and analogy to cosmic strings
a-b, (left) Polarizing optical micrographs of vortex dimers formed by vortices with (a) k = -2 and k = 2 and (b) k = 3 and k = -3, obtained under crossed polarizers (double yellow arrows). (2 middle panels) Optical soliton trajectories of 650 nm laser beam closely match (right) computer-simulated trajectories shown atop of the associated n(r) (white cylinders). All scale bars are 200 μm.
