Plasmonic enhancement of nonlinear light-matter interaction can be achievedvia dedicated optimization of resonant plasmonic modes that are spectrallymatched to the different wavelengths involved in the particular nonlinearoptical process. In this work, we investigate the generation and enhancement ofbroadband four-wave mixing (FWM) in a plasmonic azimuthally chirped grating(ACG). The azimuthally varying grating periodicity in an ACG offers awell-defined channel to mediate the near field and the far field over a broadrange of wavelengths. However, the particular mechanism responsible for fieldenhancement in such a platform depends on the interplay between the effectsmanifested by both the groove geometry and the grating's periodicity. This workdelineates the collective contribution of groove geometry-dependent localizedsurface plasmon resonance (LSPR) and periodicity-dependent plasmonic surfacelattice resonance (PSLR) over a broad range of wavelengths to bring into effectthe enhancement of broadband FWM in an ACG.
