Experimental demonstration observes transitions of topological zero edge modes in 1D lattices, suggesting new possibilities in photonics.
We experimentally demonstrate the first instantiation of a topologically nontrivial Hamiltonian with the Surface Nanoscale Axial Photonics (SNAP) platform. We observe the transition of topological zero edge modes between highly localized and delocalized regimes.
