Four-wave mixing Floquet topological solitons [PDF]
Optics Letters, 2021 We consider a topological Floquet insulator realized as a honeycomb array of helical waveguides imprinted in a weakly birefringent medium. The system accounts for four-wave mixing occurring at a series of resonances arising due to Floquet phase matching.
