The article discusses the development of photonic Floquet topological insulators, which are photonic lattices that exhibit topologically protected transport on their edges without the need for external fields. The authors theoretically propose and experimentally demonstrate the first photonic topological insulator, composed of an array of helically coupled waveguides arranged in a honeycomb lattice. This system breaks chiral symmetry, leading to scatter-free, one-way edge states that are topologically protected from scattering. The topological protection is achieved by the chirality of the waveguides, which prevents backscattering into the bulk of the lattice. The article also explores the experimental setup and results, including the observation of light confinement to the edges and the demonstration of topological edge states through various experiments and simulations. The findings suggest that photonic Floquet topological insulators could have applications in optical isolation and robust photon transport, potentially leading to new platforms for understanding and probing topological protection in the optical regime.The article discusses the development of photonic Floquet topological insulators, which are photonic lattices that exhibit topologically protected transport on their edges without the need for external fields.
