Single Molecule Nonlinearity in Plasmonic Waveguides — •Christian Schörner and Markus Lippitz — University of Bayreuth, Germany

Past room temperature experiments of single quantum emitters coupled to plasmonic waveguides have mainly focused on the highly efficient channeling of the spontaneous emission into waveguide modes. However, quantum emitters can interact with multiple optical fields leading to functional all-optical control capabilities in waveguide circuits. Here, we realize a nonlinear optical experiment, where a pump and a red-shifted depletion pulse interact fully remotely with a single molecule via propagating gap-plasmons. A saturation of the molecules' stimulated emission via confined gap-plasmons is found, that can be up to 50 times more efficient compared to a diffraction limited far-field focus.
