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]
Nat CommunQuasi-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.

Experimental analysis of four-wave mixing in a semiconductor optical amplifier using frequency resolved optical gating [PDF]
, 2007 Four-wave mixing was performed in a multi-quantum well semiconductor optical amplifier in order to demultiplex 2 ps pulses from 80 GHz to 10 GHz. The demultiplexed pulses were measured using frequency resolved optical gating.

Pump-probe detuning dependence of four-wave mixing pulse in an SOA [PDF]
, 2007 Four-wave mixing (FWM) between 2-ps pulses in a multiquantum-well semiconductor optical amplifier (SOA) is presented. The conjugate pulses are fully characterized using the frequency-resolved optical gating technique.
