WebDec 2, 2024 · The aim of this work is to show that such Floquet topological lasers exhibiting stable disorder- and defect-immune lasing in topologically protected edge states can be implemented using truncated honeycomb arrays of helical waveguides written or fabricated in the nonlinear optical material with gain saturation. WebDec 22, 2024 · As a result of the optical Kerr nonlinearity of the ambient glass, the solitonlike wave packet forms a long-lived quasilocalized coherent structure that slowly radiates power into the bulk and along the edge. The realization of solitonlike edge states paves the way to an understanding of nonlinear and interacting topological systems. 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. list of german aircraft ww2
