Route to high-resolution scanning optical microscopy — •Daniel Friedrich, Heiko Groß, and Bert Hecht — Nano-Optics and Biophotonics Group, Experimental Physics 5, University of Würzburg, Germany

Using confined photons for atomic-scale spectroscopic imaging offers new possibilities in high-resolution scanning optical microscopy and enhanced light-matter coupling. Recent investigations employ scanning probe microscopy to reveal strong coupling between single quantum dots and a single crystal broadband nanoresonator.(1)

By tuning the coupling strength between a plasmonic resonator and single quantum dots, (bio-)molecules or novel 2D-materials using scanning probe microscopy we expect new spectroscopic information with nanometer spatial resolution. Measuring photoluminescence and Raman scattering over the full visible range, in combination with state-of-the-art scanning probe technology with different optical accesses paves the way to novel spectroscopic imaging modalities and observation of a single-photon non-linearity.
