The ?ourishing of topological photonics in the last decade was achieved mainly due to developments in linear topological photonic structures. However, when nonlinearity is introduced, many ...

A research team recently discovered a novel kind of topological edge soliton that is independent of magnetic field. The valley Hall edge soliton inherits its topological protection from its linear ...

The valley Hall edge soliton inherits its topological protection from its linear counterpart and does not require any external magnetic field.
