Abstract

I provide a novel concept of Tip-Enhanced Cavity-Spectroscopy (TECS) overcoming the limitations of previous approaches to induce, probe, and dynamically control ultra strong light-matter interactions. Furthermore, I provide several new directions of nano-spectroscopy and-imaging, which have not been thought in the near-field optics community before. First, we exploit extremely high tip-pressure (approximating GPa scale) to directly modify the lattice structure and electronic properties of materials. Second, we dynamically control the near-field polarization by adopting adaptive optics technique to near-field optics. Third, we develop conductive TECS to modify electrical properties of materials by directly flowing an electric current through the cavity junction.
