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.

Optically programable quasi phase matching in four-wave mixing [PDF]
Nature CommunicationsQuasi-phase matching (QPM) enhances nonlinear optical processes by compensating for phase mismatch, but traditional methods require permanent material modifications, limiting applicability in centrosymmetric media like standard optical fibers.
