Abstract

We demonstrate nonlinear valley-Hall edge states (VHESs) in cw-laser-written anisotropic photonic lattices hosting type-II Dirac points. These topological gap quasi-solitons are fundamentally distinct from linear type-I VHESs and from all previously found topological solitons.

ii型狄拉克晶格中的非线性谷霍尔边缘态

我们证明了含有ii型狄拉克点的激光写入各向异性光子晶格中的非线性谷霍尔边缘态(VHESs)。这些拓扑间隙准孤子从根本上不同于线性i型VHESs和以前发现的所有拓扑孤子。
