Abstract

Two-photon induced photoluminescence (TPL) microscopy has been used to probe the local field of nanoantennas. We demonstrate that TPL imaging is directly correlated to the antenna electromagnetic mode computed with a full 3D solver. Furthermore, spectroscopic mode mapping while scanning the incident wavelength enables near-field spectroscopy of specific areas of the antenna response, providing a deeper insight into its resonant properties.
