WebWe present the first realization of soliton-like unidirectional edge modes on photonic Floquet topological insulators. These nonlinear modes radiate power at a finite and controllable rate because of the intrinsic gaplessness of the topological spectrum. WebJul 12, 2016 · We denote succinctly this theoretical formulation as flat optics for LWs. This formulation is based on an adiabatic, asymptotic form of the Floquet theorem, introduced here for the first time. The adiabatic Floquet-wave analysis allows for: 1) describing the mechanism of global interaction between the cylindrical surface wave (SW) launched by ...
