Design of plasmonic probe tips to control light on the nanoscale for imaging and spectroscopy with ultrahigh spatial and temporal resolution
EMSL Project ID
38203
Abstract
The optical probing of matter with simultaneous nanometer spatial and femtosecond temporal resolution has remained a great challenge. Here, using focused ion beam milling we will tune the optical antenna properties of scanning probe tips to achieve a spatially confined optical excitation with desired frequency and temporal characteristics. This provides access to the dynamics of mesoscopic phenomena at the dimensions of the electron or phonon scattering length scales for the first time in, for example, molecular nanocomposites and transition metal oxides. In addition, the new ability to probe the near-field vector distribution of nanophotonic and plasmonic devices with nanometer resolution in 3D provides a much needed design tool, offering a high technological potential for optical antenna-coupled molecular sensors, biomedical diagnostics, optical waveguides, and switches.
