The nonlinear response of sub wavelength nano-cavities in thin metal films is
investigated. We report the resonant dependence of the Second Harmonic
Generation by individual triangular and square holes on shape, size and
wavelength. For cavities with internal nano-corrugations, giant field
enhancements are observed, making them excellent candidates for high
sensitivity spectroscopy.
