We report a quantitative analysis of the wavevector diagram emitted bynonlinear photoluminescence generated by a tightly focused pulsed laser beamand distributed along Au nanowire via the mediation of surface plasmonpolaritions. The nonlinear photoluminescence is locally excited at keylocations along the nanowire in order to understand the different contributionsconstituting the emission pattern measured in a conjugate Fourier plane of themicroscope. Polarization-resolved measurements reveal that the nanowirepreferentially emits nonlinear photoluminescence polarized transverse to thelong axis at close to the detection limit wavevectors with a small azimuthalspread in comparison to the signal polarized along the long axis. We utilizefinite element method to simulate the observed directional scattering by usinglocalized incoherent sources placed on the nanowire. Simulation resultsfaithfully mimic the directional emission of the nonlinear signal emitted bythe different portions of the nanowire.
