DOI: 10.1088/1402-4896/accabb
Abstract: Modulational instability in topological photonic lattices enables the selective population of energy bands and generation of steady-state wavefields with well-defined topological invariants. This provides a way to measure bulk topological invariants, which determine the number… read more here.
