Topological Landau–Zener nanophotonic circuits

Topological edge states (TESs), arising from topologically nontrivial phases, provide a powerful toolkit for the architecture design of photonic integrated circuits, since they are highly robust and strongly localized at boundaries topological insulators. It is desirable to be able control TES transport in implementations. Enhancing coupling between TESs finite-size optical lattice capable exchanging light energy lattice, hence facilitating flexible transport. However, existing strategies have paid little attention enhancing effects through effect. Here, we establish bridge linking interaction using Landau–Zener model so as an alternative way modulate/control modes. We experimentally demonstrate edge-to-edge with high efficiency telecommunication wavelengths silicon waveguide lattices. Our results may power up various potential applications photonics.
