Abstract

The PT-symmetry breaking for topological defectstates are studied in SSH micro-resonator laser arrays. For defect modes, the PT-symmetry breaking threshold reduces when the coupling strength between closely paired elements is increased. Such topological defect-modes are demonstrated in a 16-ring SSH PT-laser arrangement.
