What is it about?
We demonstrate experimentally the transference of energy from one edge into the other on a photonic lattice. We use the topological properties of the system to observe a more robust transfer, in comparison with conventional lattice systems.

Why is it important?
While the light is traveling across a given system, the possibility of scattering effects due to any inhomogeneity at the bulk is very high, causing that the information could be lost. In our work, we experimentally demonstrated that a special (topological) material possessing very localized states at the edges could be used to offer a more robust solution without the need of interacting strongly with the bulk and, therefore, allowing the energy to be transferred, from one edge into the other, with a higher fidelity.
