Vortex light states in higher-order topological lattices

Researchers report the existence of vortex light states that are trapped at the core of lattices with a special 'higher-order' topological structure. These vortex states bifurcate from linear counterparts, have controllable localization and propagation properties set by their power, and exhibit enhanced stability due to the lattice topology. The global rotational symmetry of the lattice also restricts possible vortex charges. Overall this demonstrates new opportunities from harnessing topology to stabilize complex light states for applications.
