Resonance fluorescence of a single molecule under near field excitation

We report here theoretical investigations on the resonance fluorescence of a two‐level molecule, probed by the near field optical microscopy technique in illumination mode. The proposed model considers the influence of a coated tapered fiber probe on the radiative properties of the molecule. It is observed that both the radiative decay rate as well as the fluorescence power depend sensitively on the position and direction of the transition dipole of the molecule.
