| contents | Topological edge states manifest spin-momentum-locking propagation as a primary consequence of topological crystals. However, experimental studies on spin manipulation and the resulting propagation of these states are lacking. Here, we demonstrate experimentally spin manipulation of topological edge states by the boundary conditions of the one-dimensional path. Armchair boundaries at the endpoints of the path induce spin-flipping back-scattering, resulting in a novel one-dimensional resonance -- traveling resonance. Remarkably, we demonstrate lasing of this one-dimensional traveling resonance. Our findings hold significant potential for practical applications in spin manipulation of light. |
