Vector Topological Edge Solitons in Floquet Insulators

13 Mar 2020 Ivanov Sergey K. Kartashov Yaroslav V. Szameit Alexander Torner Lluis Konotop Vladimir V.

We introduce topological vector edge solitons in a Floquet insulator, consisting of two honeycomb arrays of helical waveguides with opposite directions of rotation in a focusing nonlinear optical medium. Zigzag edges of two arrays placed in contact create a zigzag-zigzag interface between two structures with different topology... (read more)
